A lot of the time you can check out the perma banned member thread in off topics section for the reason, or take a look at the poster's last few posts. Sometimes reading their posts you can have a good laugh watching as the guy got himself banned.

I can please only one person per day. Today is not your day. Tomorrow isn't looking good, either.
