Combot now supports a new captcha mode (as a Telegram Mini App), which significantly harder for bots to bypass than a standard button in chat.
New members who do not complete the challenge within 12 hours will be kicked, and their join request will be rejected.
Free for all groups. To enable:
Moderation → New users → Captcha → Mini App.💡 We recommend enabling join request approvals for your group. This allows Combot to send the captcha privately to each new member via DM, keeping your chat clean. Otherwise previous welcome message will always be deleted, remaining the last one.
