I only ever read and post in the audio play forum, and while I've only been reading it for a couple of months, it seems pretty civil there at least. But I have heard many horror stories about the board in general, so I'm not surprised by this situation, unfortunately.
Towards the end of my interest in Who as a big fan (I now class myself as 'casual') I only stayed in forums that dealt with missing episodes. While it was fun, the same old information kept getting thrown around and a lot of the time newbies were jumped on and the correct information shoved down their throats before they had chance to call for help.
It wasn't the best, and lead to my eventual departure from fandom in general.
Except for this forum/bbs, of course.
