I have a terrible cold right now, and can't think straight, but I'm going to give this a go. I'll try to explain step by step what happens when various types of people are banned (as there are several differences between them all, and trying to gloss over things for the sake of being simple only makes things more confusing)
I shall use examples:
1. Pecker, banned for gender faking / multiple accounts(I'm ill ok)
He returns under a new name and goes about posting in various threads about "her" experiences and such, maybe dabbles in a little politics and generally stays out of peoples way, causing little to no harm outside of getting straight men to wank on cam for him assuming he's a woman.
He's caught however because he happens to join chat while Flamey is in there and he recognises the lines being spun as those used previously by Pecker.
A quick check and there is enough to confirm that he's back and on this new account, so after all the facts have been put in the mod forum, discussed and voted on, we ban him.
We don't remove his posts on the board because they're doing no harm to anyone, don't enable him to continue conning the membership and people have replied, with quotes and removing them would leave things very messy for the sake of "not letting him have his say"
2. Flamey, banned for attacking people in the chat room repeatedly and without any cause.
He comes back under a new name and starts threads, blogs, replies to random threads all bitching about other members, distributing lies and just being a bit of a cunt all round.
Based on the content of these, we obviously have a fair idea of who it is, so we do the usual checks, confirm it and he's gone.
In this case, the posts and his account are flagged up pretty quick and have caused limited disruption to the board, he's been removed and removing the posts stops people responding which only encourages him to return again to reply to said replies. Had he rejoined and stayed under the radar for a few months before losing it all and going on his little rant fest, earlier posts may well remain in tact.
3. Hickboy, banned for being a minor.
He returns and makes 3 posts in various sections, one asking about his size at 14yo, and 2 containing his email addy.
He's banned and his posts are all removed, for obvious reasons.
The long and short of it all is this: Almost every case is different, and as a team we spend hours, sometimes days debating what should and shouldn't be done with x issue. None of us claim to always get it right, but we can say that we always go with what the majority wish at the time. It all comes down to the content of the individual posts, their intent and the possible outcomes of our actions.
I'm sorry that people aren't happy with the decision currently being discussed, and I'm sorry that explaining why it was that way for x member on y account, and this way for y member on z account is so difficult, but the very simple fact is that while consistency is lovely and always something we try to keep up, rigid consistency isn't a good thing... we ban for multiple accounts, but several in this thread alone have had more than one to log on and let us know there seems to be a problem with their accounts, would you have us ban them? Consistency says we should (a bad example maybe, but you get my point I'm sure)
