How to stop scammers joining your Telegram group
Use a public entry point with CAPTCHA, put the real community in a private group, and issue one-time invites. Then run admin impersonation detection inside the room, because human scammers can still pass a join challenge and clone trusted staff.
Why open joins invite scams
Crypto Telegram groups get hit in layers: mass bot joins, drive-by link spam, and quieter identity clones that look like admins. A fully public room makes browsing and DM targeting easy even for people who never become members. Entry control shrinks that surface. It does not replace identity protection after someone is inside.
Steps to stop scammers joining
- Decide what must stay private. Move member chat, support, and holder discussion into private groups so outsiders cannot browse history or harvest usernames without joining.
- Keep one public entry point. Use a public @ or channel for discovery, then route verified people into the private room instead of leaving the full chat open.
- Require CAPTCHA before invite. Add a Portal or join CAPTCHA so automated join bots fail before they receive a working invite.
- Issue one-time invites. Prefer invites that expire on use so a forwarded link does not become a permanent open door.
- Detect admin clones inside the room. CAPTCHA stops many bots at the door. Identity clones that pass as human still need display-name and profile-photo checks after they join.
- Pin the never-DM-first rule. Tell members that real admins never DM first and never ask for seeds, wallet signatures, or login codes.

FAQ
Will CAPTCHA alone stop Telegram scammers?
No. CAPTCHA reduces automated joins. Human scammers can still pass verification, copy an admin identity, and DM members. Pair entry gates with anti-impersonation and clear DM rules.
Should my crypto Telegram group stay public?
Public groups are easy to find, but they often expose history and member surfaces to people who never join. Many teams keep a public @ for discovery and hold the real community in a private group behind CAPTCHA.
How does BeefyGuard help stop scammers from joining?
BeefyGuard Portals add CAPTCHA on a public entry chat and issue one-time invites into private groups. Inside the room, BeefyGuard detects admin display-name and profile-photo impersonation so clones can be banned before they scam in DMs.
