To join Bangladesh Hindu Samaj, you must have a Telegram account. All member communication happens only through Telegram. We all work remotely. Wherever you live, you can still serve your home district. All weekly meetings will happen through Telegram group video or audio calls. Face-to-face meetings will take place on the first Friday of every month or during special events.

For your safety, never share your phone number with strangers or on social media. Keep your phone number hidden on Telegram. After creating your Telegram account, set a username. Add _bdh at the end of your username.
For example, if your name is Pranab Kumar Sen, choose: pranab_bdh.
If not available, try pranabkumar_bdh, pranab1_bdh, or pranab2_bdh.

What is Telegram?

Telegram is a messaging app focused on speed and security. It is fast, simple, and free. You can use Telegram on all your devices at the same time. Your messages sync easily across your phone, tablet, and computer. Telegram is one of the top 5 most downloaded apps in the world with over 950 million active users.

You can send any type of message, photo, video, or file (doc, zip, mp3, etc). You can also create groups with up to 200,000 members or channels with unlimited audiences. You can message phone contacts or search by username. Telegram works like a combined SMS and email system, perfect for both personal and business communication.

How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with continuous syncing. This lets you access your messages on many devices at once, including tablets and computers. You can share photos, videos, and up to 2 GB files easily.

Telegram takes less than 100 MB on your device. You can keep all media in the cloud. Just clear the cache when you need storage.

Telegram is faster and more secure because of its multi-data-center design and encryption. Personal messaging is free and will always remain free — with no ads and no subscription fees.

Which devices support Telegram?

You can use Telegram on smartphones, tablets, and computers. There are apps for iOS 11+, Android 6.0+, a native macOS app, and a universal desktop app for Windows, macOS, and Linux. You can also use Telegram Web for quick access.

2 - How to Create a Free VPN Account – A Complete Guide

We request all our members to learn how to use VPN properly and use it when needed. If authorities ever block our site, Telegram, Facebook, or WhatsApp, you will be able to access them easily through VPN.
How to Create a Free VPN Account
How to Create a Free VPN Account

Why You Should Use a VPN

We request all our members to learn how to use a VPN properly and be capable of using it when needed. If authorities ever block our site, Telegram, Facebook, or WhatsApp, a VPN will help you access them without issues. So install the ProtonVPN app on your phone now. Is VPN legal in Bangladesh? Yes, VPN is legal in Bangladesh. Encrypt your data, hide your IP, and browse freely. But remember, with or without VPN, we never support breaking laws or licenses.

A Virtual Private Network (VPN) is a cybersecurity tool that encrypts your internet connection and protects your online privacy. It creates an encrypted tunnel between your device and the server, hiding your IP address and securing your data from unwanted tracking. The purpose is simple — enhance your online privacy and safety, protect your device from online threats, and allow uncensored browsing. It hides your real location and gives you privacy, especially while using public Wi-Fi.

Why Use VPN in Bangladesh

The Bangladesh Telecommunication Regulatory Commission (BTRC) often censors the internet, especially political content and social media posts. Recently, BTRC has begun a large-scale surveillance program and proposed new laws that might require storing and collecting user internet data. This is why using a VPN helps you bypass online censorship and monitoring.

Step 2: Connect to a Server

You can auto-connect to the fastest server for your location or choose any available server on your plan.

Your data is encrypted between your device and the VPN server, meaning:

  • Your ISP cannot monitor your activities.
  • Websites see the VPN server’s IP, not yours.

While connected, check your IP to confirm the VPN is active.

How to Use Proton VPN on iPhone and iPad

Step 1: Download and Log In

Download Proton VPN from the App Store and install it on your iPhone or iPad. Open the app and log in with your Proton VPN username and password.

Download Proton VPN for iOS

Step 2: Connect to a Server

You can auto-connect to the fastest server or choose any server available in your plan.

Your data is encrypted between your device and the VPN server, meaning:

  • Your ISP cannot track your activity.
  • Websites see only the VPN server’s IP.

While connected, check your IP to confirm the switch.

What Is a VPN Ban?

A VPN ban is when governments, organizations, or ISPs restrict VPN usage. They may block VPNs to stop users from bypassing censorship or hiding activity. VPN traffic is identified and blocked using detection technologies, making VPN access limited or fully restricted.

Can VPN Be Blocked?

Yes, VPNs can be blocked. Governments and organizations may block VPNs to impose censorship or protect internal networks.

How to Know If Your VPN Is Blocked?

You may face the following issues:

  • Connection failure
  • Unable to connect to any server
  • Websites not loading
  • IP remains unchanged even after connecting
  • VPN stops working on specific networks

How to Bypass a VPN Block?

If you wish to bypass restrictions, ensure it is legally allowed and follows local laws and network policies. Otherwise, it may cause legal issues. If the use is not illegal, you may try:

  • Changing VPN protocol
  • Switching to mobile data

How Are VPNs Blocked?

Governments or companies use several methods to block VPNs. They may collect the list of IPs used by a VPN service and block them. Firewalls may also be configured to block VPN ports. If you try connecting through a blocked port, the request is rejected.

They also use Deep Packet Inspection (DPI) to analyze data between your device and the server. DPI detects VPN-specific patterns and signatures. Once detected, the VPN connection is blocked.

3 - False Blasphemy Traps in Bangladesh

In recent years, some people in Bangladesh have faced serious trouble due to false blasphemy accusations. These accusations can spread fear, damage lives, and break community trust. Many ordinary people do not understand how such situations begin or why they spread so fast. Learning about this topic helps communities understand risks, recognize patterns, and stay aware of how everyday actions—especially online—can be misused by others.

False Blasphemy Traps in Bangladesh: How Innocent Hindus Are Targeted—and How to Stay Safe

Introduction: Why This Topic Matters

In recent years, some people in Bangladesh have faced serious trouble due to false blasphemy accusations. These accusations can spread fear, damage lives, and break community trust. Many ordinary people do not understand how such situations begin or why they spread so fast. Learning about this topic helps communities understand risks, recognize patterns, and stay aware of how everyday actions—especially online—can be misused by others.


Background: Why False Blasphemy Cases Happen

False blasphemy cases do not usually happen by accident. They are often planned carefully for personal gain.

In simple terms, a false blasphemy case means someone is wrongly accused of insulting religion, even though they did not do so. These accusations are sometimes created to harm a person or family.

Why such accusations are created

  • Some groups use false accusations to take over land or property.
  • Business rivals may try to remove someone from competition.
  • A person may be targeted at work to push them out or isolate them.
  • Families may be forced to leave their homes due to fear.

How these accusations are spread

  • Fake social media posts are created in someone’s name.
  • Images or messages are edited to look offensive.
  • Old or hacked accounts are used to post false content.

What often follows

  • Large groups gather quickly without checking facts.
  • Pressure is created by powerful or organized groups.
  • Victims often stay silent due to fear of harm.

Understanding this background helps people see that these cases are often about power and control, not religion.


Common Methods Used to Trap Innocent People

False accusations often follow similar patterns, especially online.

How people are targeted

  • A social media account is created or hacked using the victim’s name.
  • False or offensive content is posted and blamed on the victim.
  • People are provoked into emotional replies that are later misused.
  • Fake profiles with familiar names are added to friend lists.
  • Old or forgotten accounts are taken over because they are not protected.

These methods work because many people trust what they see online without checking the source.


Understanding Commonly Suggested Safety Measures

Many community discussions focus on digital safety. These points are often shared to explain how online activity can affect real life.

Social media hygiene

This refers to basic care of online accounts.

  • Strong passwords reduce the chance of account misuse.
  • Extra login steps help confirm the real account owner.
  • Checking login activity helps notice unusual access early.

Privacy controls

Privacy settings decide who can see or share posts.

  • Limiting visibility reduces misuse by strangers.
  • Controlling comments and sharing reduces misinterpretation.
  • Reviewing tagged posts avoids unwanted public display.

Account management

Inactive or forgotten accounts are often misused.

  • Recovery keeps control with the original owner.
  • Deletion removes unused accounts from risk.
  • Searching one’s name helps notice fake profiles.

Online behaviour

Online conversations can be misunderstood.

  • Neutral language reduces the chance of conflict.
  • Saving suspicious messages helps document events.
  • Informing trusted people spreads awareness early.

These practices are discussed because online actions often have offline consequences.


Understanding High-Risk Online Mistakes

Certain online actions are often linked to higher risk in tense environments.

Online interactions

  • Religious or political discussions can be misquoted.
  • Emotional replies are easier to misuse than calm silence.

Friend requests

  • Some fake profiles use familiar names or photos.
  • New accounts with little activity are harder to verify.

Posting habits

  • Public posts reach unknown audiences.
  • Jokes, symbols, or trending topics can be misunderstood.

Multiple accounts

  • Extra or forgotten accounts are easier to hijack.
  • Each unused account increases risk exposure.

Understanding these risks helps people see how small actions can lead to serious outcomes.


Community-Level Awareness

Safety is not only individual. It also involves the wider community.

  • Trusted offline relationships help verify information.
  • Sharing knowledge builds collective awareness.
  • Clear records of land, work, and identity reduce disputes.
  • Document copies help establish facts during conflict.

When communities are informed, false stories lose power.


When a Threat or Accusation Appears

False accusations often spread quickly and emotionally.

  • Public reactions can increase tension.
  • Digital records help clarify what actually happened.
  • Family and community elders often provide guidance.
  • Reduced online activity lowers immediate exposure.

Understanding these responses helps people remain calm during stressful moments.


Conclusion: The Value of Awareness

False blasphemy traps rely on fear, confusion, and lack of information. Learning how these situations develop helps communities stay alert and informed. Awareness does not remove risk, but it helps people recognize patterns early and understand the importance of careful digital and social behavior. Knowledge strengthens communities by replacing fear with understanding.


Introduction

Many false accusations and misunderstandings today begin on social media. People often do not realize that small settings inside apps like Facebook, Instagram, YouTube, or WhatsApp can decide who sees their content and how it can be used. This section explains, in very simple language, how these platforms work and why people talk about setting them carefully. The purpose is to help readers understand what these settings mean and how online activity can affect real life.


Facebook: Understanding Basic Account Safety and Visibility

What Facebook Is in Simple Terms

Facebook is a place where people share thoughts, photos, and messages. What many do not realize is that Facebook is also public by default unless settings are changed.

Why Facebook Settings Matter

Anything visible to “Public” can be seen by strangers, saved, edited, or shared outside Facebook. This is why many problems start here.

Key Areas People Talk About

Profile and Posts Visibility

  • Facebook allows posts to be seen by:

    • Everyone (Public)
    • Only friends
  • Public posts can spread very fast without control.

Friends List Awareness

  • Anyone on a friends list can see personal posts.
  • Fake profiles sometimes look real and friendly.

Old Posts and Tags

  • Old posts may still be visible.
  • Others can tag a person in posts or photos.

Why This Affects Daily Life

A single misunderstood post or tag can be copied and shown outside context. Many people face trouble because they forgot what was posted years ago.


Instagram: Understanding Photos, Stories, and Followers

What Instagram Is

Instagram mainly shares photos, short videos, and stories. Many users think it is harmless because it feels casual.

Why Instagram Can Create Risk

Images and short text are easy to misunderstand. Screenshots can be taken silently.

Important Things People Should Understand

Public vs Private Accounts

  • Public accounts can be viewed by anyone.
  • Private accounts limit viewing to approved followers.

Followers and Messages

  • Anyone can send message requests.
  • Fake profiles often follow first, then provoke conversations.

Stories and Reels

  • Stories disappear visually but screenshots remain.
  • Reels can reach unknown viewers if public.

Community Impact

A single image or caption, when taken out of context, can create serious misunderstanding beyond Instagram.


YouTube: Understanding Comments and Channels

What YouTube Is

YouTube is mainly for watching and posting videos. Even people who do not upload videos often comment.

Why Comments Matter

Comments are public and searchable. Even old comments can resurface later.

Areas Often Overlooked

Commenting on Videos

  • Comments stay visible for years.
  • Arguments in comment sections are often recorded by others.

Channel Activity

  • Even an inactive channel shows comment history.
  • Profile names and photos are visible publicly.

Why Average Users Should Care

Many people forget what they commented on months or years ago. Screenshots of comments can be misused later.


WhatsApp: Understanding Groups and Messages

What WhatsApp Is

WhatsApp is used for private messages and group chats. Many people feel it is fully private, but this is not always true.

How WhatsApp Content Spreads

  • Messages can be forwarded.
  • Screenshots can be taken.
  • Group messages reach many people quickly.

Group Membership

  • Anyone in a group can save messages.
  • Not all group members are personally known.

Group Discussions

  • Heated discussions often happen in groups.
  • Messages sent in emotion are hard to control later.

Why This Matters in Daily Life

Many misunderstandings begin inside WhatsApp groups and later appear outside the group without explanation.


General Understanding Across All Platforms

One Common Reality

  • Online content does not disappear easily.
  • Even deleted content may already be saved by someone else.

Why People Talk About Digital Caution

  • Online words can be separated from context.
  • Images and text can be edited.
  • Silence or limited sharing reduces misunderstanding.

How Awareness Helps

  • People understand how platforms work.
  • Communities learn why small actions matter.
  • Fear reduces when knowledge increases.

Conclusion: Learning Before Reacting

Social media platforms are tools. They are not good or bad by themselves. Problems arise when people do not understand how visible their actions are. Learning how Facebook, Instagram, YouTube, and WhatsApp function helps people stay informed and calm. Awareness does not stop all risks, but it helps people recognize situations early and understand why careful online behavior is often discussed in community safety conversations.


Immediate Check: Reviewing and Securing Your Existing Social Media Profiles

Why This Immediate Check Is Important

Many people face problems not because of new posts, but because of old posts, forgotten settings, or unused accounts. Content shared years ago, or posted by someone else and linked to your name, can still be seen today. That is why it is important to check profiles immediately, even if you are not active online.

This section explains, in very simple language, what people should look for and understand right now.


First Step: Check Your Profile Today

The first step is to open each social media app you use and look at your profile as a stranger would see it.

  • Check your profile photo, name, and bio
  • Scroll through old posts
  • Look at comments and tags
  • See who can view your content

Many people are surprised to see how much is still public.


Making All Posts “Friends Only”

What “Friends Only” Means

“Friends only” means:

  • Only people you personally accepted can see your posts
  • Strangers and unknown users cannot view or share them

This setting is important because public posts can travel far beyond your control.

Making Past Posts Safer

Most platforms allow users to:

  • Change all old public posts to “Friends only”
  • This includes posts made many years ago

People often forget old posts, but others may not.


Disabling Tagging and Review Options

What Tagging Is

Tagging allows others to:

  • Add your name to posts or photos
  • Make that content appear on your profile

Why Tagging Can Be Risky

  • You may be tagged in content you did not create
  • Others may misunderstand the context
  • Screenshots may spread without explanation

What to Look For

  • Options that allow you to:

    • Review tags before they appear
    • Stop others from tagging without permission

This helps keep control over what appears under your name.


Deleting Old or Unused Profiles

Why Old Profiles Are Dangerous

Old or unused accounts are often:

  • Forgotten
  • Poorly protected
  • Easier to misuse or hack

These accounts can be used to:

  • Post false content
  • Impersonate the original owner

Platforms Where This Is Common

  • Facebook
  • Instagram
  • YouTube

If an account is no longer used, it is safer to delete it completely.


If You Do Not Know How to Change These Settings

Many people are not familiar with app settings, and that is normal.

If you feel confused:

  • Ask a trusted family member
  • Ask someone younger or more familiar with smartphones
  • Sit with them and check settings together

There is no shame in asking for help. Learning together strengthens safety.


A Simple Reminder for Everyone

  • Old posts still exist
  • Public content spreads quickly
  • Forgotten accounts carry risk
  • Small setting changes can reduce misunderstanding

Closing Note: Awareness Starts With One Check

Checking your social media profile today is a simple but powerful step. It does not require technical knowledge or special skills. It only requires attention and time. Understanding what is visible under your name helps reduce confusion, fear, and misuse. Awareness begins with looking, understanding, and learning—together as a community.
