I manage your telegram groups. I use TLG_JoinCaptchaBot for captchas.
-
bot protection: verify new users with captchas, auto kick spamming bots
-
log protection: let me manage your invitation links; bots can not even join your group
-
notes: add notes for your user
-
filters: add filters so I can auto-answer questions or kick/ban users that are using specifiy strings
-
connect: manage your group settings in private
-
auto-delete: I do not spam your group, messages are automatically deleted
You probably never saw a log protection like that before(I didnt).
Any usual bot-protection solution verifies "users" after they joined your group. Any bad bot can dump your whole group history before it fails the verification.
This solution verifies users before they can join your group!
- Set your group to private
- Activate Log Protection with
/protection - Tell users to ask me for an invitation link in private chat
- I will create an invitation link for the user if he passes the captcha
- I revoke the invitation link after a timeout, or after the user joined your group
- Only the verified user can join your group. If another user uses the generated link, I will kick him and revoke the link
