Discord & Telegram Public Groups: The প্রাইভেসি Risks Nobody Talks About

Public groups on Discord and Telegram are powerful tools for finding communities around shared interests. But joining an open server or group exposes more personal information than most people realize. From your profile details to your online activity patterns, the data trail you leave behind can be exploited by bad actors.

What Information You're Exposing

Profile Data Exposure

Exposed Data	Discord	Telegram	Risk Level
Username	Always visible	Always visible	Medium
Profile photo	Always visible	Always visible	High
Phone number	Hidden by default	Can be exposed in settings	Critical
Online status	Visible to server members	Visible to everyone by default	Medium
Linked accounts	Visible if enabled	N/A	High
Bio/About	Visible to server members	Visible based on settings	Medium
Mutual servers	Visible to members	Mutual groups visible	Medium

Real-World Risks

• Doxxing: Piecing together information from your profile, posts, and linked accounts to reveal your real identity
• Social engineering: Using personal details shared in groups to craft targeted scams
• Stalking: Tracking your online activity patterns across servers and groups
• Account theft: Using information from public groups to answer security questions
• Spam and ফিশিং: Mass-targeting group members with scam DMs
• Employer discovery: Your participation in certain groups could be professionally damaging

Discord প্রাইভেসি সুরক্ষা

1. Create a Separate Account for Public Servers

Don't use the same Discord account for personal friends and public communities. Create a dedicated account with:

• A username that doesn't connect to your real identity
• No linked social media accounts
• A generic profile picture
• No identifying information in your bio

2. Adjust প্রাইভেসি Settings

Settings > প্রাইভেসি & Safety:

• Turn off "Allow direct messages from server members"
• Enable "Keep me safe" for message scanning
• Disable "Allow access to age-restricted servers" unless needed

3. Manage Server-Specific Profiles

Discord allows per-server nicknames and avatars. Use different identities across servers, especially for sensitive communities.

4. Control Who Can Add You

• Disable friend requests from server members
• Require mutual friends for friend requests
• Don't accept friend requests from unknown users in public servers

5. Review Connected Accounts

Settings > Connections — remove any linked accounts (Steam, Spotify, Twitter) that you don't want publicly visible.

Telegram প্রাইভেসি সুরক্ষা

1. Phone Number Visibility

This is Telegram's biggest প্রাইভেসি gap. By default, your phone number can be visible to group members.

Settings > প্রাইভেসি and Security > Phone Number:

• Set "Who can see my phone number" to "Nobody"
• Set "Who can find me by my phone number" to "My Contacts"

2. Profile Photo Restrictions

Settings > প্রাইভেসি and Security > Profile Photos:

• Set to "My Contacts" to prevent strangers from seeing your photo

3. Forwarded Messages

When someone forwards your message, it can link back to your profile by default.

Settings > প্রাইভেসি and Security > Forwarded Messages:

• Set to "Nobody" to prevent forwarded messages from linking to your account

4. Group Invitation Controls

Settings > প্রাইভেসি and Security > Groups & Channels:

• Set to "My Contacts" to prevent random users from adding you to groups

Safe Communication in Public Groups

What NOT to Share

• Real name, phone number, address, or workplace
• Photos with identifying backgrounds or metadata
• Financial information (bank accounts, crypto wallets)
• Screenshots containing personal details
• Location information or check-ins
