АнтиСпамБот

"АнтиСпамБот" (user_ban_bot) is primarily an anti-spam tool, but its own feature set puts welcome messages front and center: a configurable greeting with buttons that can be automatically deleted after a set interval so the chat does not accumulate old welcome messages, plus premium options like quiet hours and removing recent joiners during a spam wave.

Because spam protection is its main job, expect message-content filtering alongside the greeting rather than a pure welcome-only tool — a reasonable trade-off if you want both in one bot instead of running two separate ones.
