I have a nasty history with the Fucking Machines square. The first two years I played, it came up on both of my cards, and I was just so... not even squicked, more scared by the thought of having to write for it that it sent me in a total tailspin and completely ruined me the second year. I think I might have got enemas on that card as well. XD I'm better with the kink now, but I was so relieved when I could start opting out of it and then actually started to manage to do bingos. It's so specific, that there's no way around it! And that's exactly the problem with a lot of the extreme categories they've introduced. I don't think they realise how much of an impact that kind of thing can have, or how much fun gets sucked out by it happening to you.
