Ban spammers before they write a single word. AI analyzes profile photo, bio, and username the moment they join.
One ban in your chat = automatically banned across ALL connected chats. Collective immunity that grows smarter.
SimHash fuzzy matching catches spam variations that keyword filters miss. Even reworded spam gets detected.
Spammers post innocent text, then edit to scam link. Every other bot misses this. We catch it.
Shieldy is free and open-source. For groups that only need to block automated join-bots, it costs nothing.
CAPTCHA guarantees that no automated bot passes through. Simple and effective against low-sophistication attacks.
