Your group's bouncer - Goodbye spammers
3 followers
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.
I built this because every Telegram crypto group and admins face the same problem - the second you open a group, the spam floods in. Spam promoters, fake admins, onlyfans bots - spamming the groups and your DMs.
Existing bots use CAPTCHAs or quizzes that annoy real users and barely slow down spammers. I built verification system that's encourages legitimate users and is lethal to bad actors. The Mini App approach lets us capture IP data server-side for country detection, which no traditional bot command can do. The global blocklist was the turning point - once a spammer fails verification in one group, they're flagged everywhere.
We added six-layer screening because no single check catches everything, but together they catch nearly everyone.
Plan to scale this beyond crypto - and allow custom ruleset per community - restricted countries, blacklist sets, bio and display name rulesets.
Built as part of the Great Teacher Onizuka ($GTO) ecosystem on Solana.
