Manual moderation is a total nightmare when bot networks target your chat. Built-in filters usually fail because spammers cycle through fresh accounts. If you want a clear breakdown of how to fix this, check out this guide for setting up group security. The best method is stopping the account first. You should enable a new member challenge so bots cannot post right away. Setting a join rate limit like ten joins per thirty seconds stops raids instantly. I set this up last month on my own chat. Spam links dropped to zero almost immediately. Give it a try now. Your chat will stay clean, quiet, and safe for everyone.
