Thread derailing. Casual Intercourse seems to be hit the worse. "[Official] Post a recent picture of yourself thread" is a prime example. I counted 13 posts about AIDS. Really? I can totally see how that's relevant to member photos.

Also, posting and typing standards for Casual Intercourse are way too low. Sometimes it feels like SFW Flames. However I have noticed that recently the really crappy threads have been trashed. I applaud this.
