And no. But there're really only two rules for BKO:
Never talk about doing illegal activities. I don't care what you say, but that kind of thing is disgusting, not to mention dangerous.
Other than that, you can do pretty much anything. I do ask that you keep your posts as tasteful as you can, though... don't just post some random garbage. I mean, aimlessness is fun, but if you're just trying to be funny but seriously failing... your thread will be locked.
Don't bother sending me messages or anything, I'm not in charge of the site anymore.
