Shieldy

Shieldy — is the best solution in Telegram to fight annoying spammers. It asks newcomers to execute a set action within a set period, otherwise it kicks them. It's this easy. Make sure @shieldy_bot is an admin at your chat and it's all done! You can also further setup the behaviour with the following commands:

/help — shows this message
/language — switches language
/captcha — changes type of captcha used
/timeLimit — changes amount of time given to newcomers
/lock — makes commands accessible only by admins
/restrict — restricts newcomers to send only text messages in the first 24 hours
/deleteEntryMessages — delete messages about user entry
/greeting — greets users who pass the test
