Captcha

Verifies that new group members are real people and not spam bots.

How does it work?

1. A new user joins the group
2. The bot sends them a message with a private link
3. In private, the bot displays an emoji captcha
4. The user selects the correct emoji
5. If correct → they can write in the group
6. If they fail (maximum attempts reached) → the configured action is triggered

Configuration

1. /config → Select group → Captcha
2. Enable/Disable — Toggle on/off
3. Timeout — Maximum time to solve (default 60 seconds)
4. Maximum attempts — Number of attempts before the action (default 5)

Notes

• Bots added by admins are exempt
• If the user does not solve the captcha in time, they are kicked
• The captcha is solved in private (does not clutter the group chat)
