What Капча для групп и чатов does
Captcha_Rubot is a no-frills checkpoint bot: it adds a captcha challenge to your group or channel-linked chat, and members who do not pass it within the time window are removed. It is built with Russian-language communities in mind, both in its own interface and in the typical spam patterns it is tuned against.
Independent comparisons group it with similar entry-level captcha bots like ZashchitaOtSpamaBot and CaptchaAntiSpamBot rather than positioning it as a full moderation suite — expect it to handle the join moment only, with no content filtering afterwards.
How to start
- Add @Captcha_Rubot to the group as admin
- New members are challenged automatically on join

FAQ
Does it filter spam messages too?
No, it only checks people at the moment they join; pair it with a moderation bot for ongoing filtering.
