Every new member who joins your Telegram group opens a Mini App and gets screened through six layers: global blocklist, IP-based country detection, display name check, bio content scan, phone country verification, and Telegram spam flags. Fail any check and you're banned instantly - and added to a shared global blocklist across all protected groups. Admins get /clean to purge unverified members in bulk. No CAPTCHAs, no quizzes, no friction for real users. One bot, zero spam.
