Call me crazy but I believe he may have been banned for at least one of two reasons....
1 - "All JAA pilots have yellow tatoos on their dicks" - not exactly the most diplomatic statement?
2 - Generally being a pain in the arse.
If you have a serious complaint about it I suggest you email one of the wannabes moderators or even Capt_PPrune but I reckon you'll get a small flea put in your ear for your troubles.
Hope this helps
