Posting stuff that irritates people is "bad". Of course, what is bad to some is good to others, so it's basically all arbitrary. Sometimes what's bad becomes Bad when it irritates someone with blue stars below their name. Of course, we blue-starred folks have to have a measure of self-restraint and not go apeshit with locking and deleting and stuff because as irritable and human as we are, we usually realise something or other that makes us not lock stuff because of free speech or something, which is the point I'm trying to make.
So anyways, in conclusion, keep blathering, but I'll remind you that this is First Class. We don't allow any riff-raff blatherers in here, y'see. That's what makes us stand out from The Fridge/General Revelry/Church of Despair.
Edit: Oh, I just had a theory. I think the type of random fluffy type of person that enjoys pillow fight threads is also the type that hates people having an interesting and/or constructive argument, or swearing, so by being mature and respecting other people's opinions and swearing a whole fucking lot, we can keep such undesirables out of town without actually imposing any sort of apartheid. It's all about voluntary banishment.
