Anyone who has been banned has broken one of the rules, thats all thats needed to really know. We dont ban for no reasons, and to sit and list every banned member that we ban would take enough time to never post.
We honestly must ban atleast 200-500+ people per day. Either from joining up and pm spamming, spamming affiliate links, to other things.
Its just not going to happen, if your interested however in knowing why someone is banned, you could usually pm a moderator.
But only with a valid reason for wanting to know why someone is banned.
