Also, some admins will ban you without warning if you are a regular on the servers (like on at least once a day), now I still think that warnings SHOULD be given out whether they are a regular or not. Whether you think they should know the rules since they're regulars, it doesn't mean that you should just ban without a proper warning. Just my opinion
BUT...just to be clear, I agree with anex, and most bans that admins/clan give out are justifiable.
