Invision has included a Warning System and I have chosen to enable it. Moderators CAN be warned. The only group that this doesn't affect is the Admin. You will get up to 3 warnings. Once you reach that, then moderators or admins will ban you. I hope that it'll never come to that :grin:

Moderators can only warn once a day. Global Moderators can warn 3 times a day.

Basically warns go for the bannable actions to a slightly lesser degree. Spamming, bad attitude/flamming towards another member or consistant profanity are the three that are pin-pointed.
