Why shouldn't I ban the one
-who edits my levels and upload it to j2o
-who is using a kill command when he is losing in a duel
-who is asking one million times for the adminpass
-who tried to use ASD on my server
-who is spamming with CAPS LOCK when he feels ignored
-who says bad words all the time =o
-etc, etc...

and changing your nickname doesn't mean that your personality also changes
