I, for one, have to sympathize with the admins. I have been the admin on many a board, a server admin on IRC, and administrated many servers around the globe. It is very hard for an admin (who usually tries to stay out of discussions for political or other reasons) to sometimes get the full gist of what a conversation is about. With many items flying up at you from all different directions, you just can't always get what's going on in a certain post. And, since many people are not so skilled in posting sarcasm, jest, or other emotions, some posts may come through wrong.
Then, there are the users who have given reason time and time again via many different conversations why they get banned "easily". A user who rubs everybody wrong at one time or another, but just shy of the ban line will get remembered quickly. Admin's don't always remember the conversation, but we remember names, faces, and definitely attitudes.
If you don't want to be the person who gets "easily" banned, don't be in the minds of the admins - we have better things to do than look for certains names to appear in discussions with high post counts! And, no matter if we get paid to do the job or not, it's the same amount of work!
