Anti-spam in depth
Message rate, duplicate and mention limits, timeouts and message deletion.
Three triggers
Anti-spam tracks each member's recent messages in memory and acts when any of three limits is passed inside the window: total messages, identical messages, or mentions in one message.
- max_messages
- Default 6 messages inside window_seconds (default 8).
- duplicate_limit
- Default 4 identical messages inside the window.
- mention_limit
- Default 6 user or role mentions in a single message.
What happens
The member is timed out for timeout_minutes (default 10) and, if delete_messages is on (default), the offending messages are removed. The log channel gets an entry with the trigger. Timed-out members cannot send messages, react or join voice until the timeout ends.
Exemptions
Members with Administrator or one of the configured admin roles are not acted on, and bot messages are not inspected. There is no separate trust list for anti-spam; if a channel should be exempt, deny the bot View Channel there.
Tuning
A hype channel during a drop will trip 6 messages in 8 seconds for normal people. Raise max_messages or lengthen the timeout rather than turning the feature off. Off by default, like anti-nuke: enable with /security antispam enabled:true or on the Security page.
