I've just set up a warning system for the Ninjas to use instead of outright banning misbehaving members. It's got varying flavors of "Fuck off" including verbal warning, post moderation, and post mute. These states decay over time and cannot be set permanently, so breathe a bit easier.
If you happen to get warned, you may or may not receive an automated PM with the reasons for your warning/restriction. I don't have it set up to have Disembodied Soul sending the PM, but I am working on that and hope to have it functioning in the near future.
Cheers.
