AutoMod
AutoMod checks every message against the rules you turn on and takes the action you choose - delete, warn, or both.
What it catches
- Spam and repeated text
- Server invites and off-site links
- Too many caps, emojis, spoilers, or mentions
- Bad words you list
Each rule can be limited to certain roles or channels, so your staff and quiet channels are left alone. Set it up under Bot settings, Moderation.
