List all warn filters
Get a users number
/warns <userhandle> gets a user's number, and reason, of warnings.
Warn a user
/warn <userhandle> warns a user. After 3 warns (can be changed), the user will be banned from the group. Can also be used as a reply.
/resetwarn <userhandle> resets the warnings for a user. Can also be used as a reply.
Adding warning filters
/addwarn <keyword> <reply message> sets a warning filter on a certain keyword. If you want your keyword to be a sentence, encompass it with quotes, as such:
/addwarn "very angry" This is an angry user.
Stopping warn filters
/nowarn <keyword> stops a warning filter.
Configuring warn's behaviour
You can use
/strongwarn <on/yes/off/no>. If set to on, exceeding the warn limit will result in a ban. Else, will just kick.
Modifying the warning limit is also quite easy:
/warnlimit <num>, where
num is a number.
