when people completely derail threads with off-topic stuffposting. personally i like stuffposting as long as its somehow vaguely on-topic with whatever thread youre posting in. but it really annoys me when people are talking about i subject i find interesting on some random thread, then someone (coincidentally very controversially well known in some way on the forum) interrupts the conversation then everyone else responds to the off-topic stuffposting rather than the on-topic posting for five pages.
