But, the thing is, there actually was one guy who kept making KSBD threads without even trying to discuss the KSBD game. It wasn't just one guy who was making KSBD threads (and some people were trying to actually discuss the KSBD game), but there was someone who was repeatedly making /co/ threads on /tg/. This upset people, and it got to the point where people started to attack any kSBD thread, just out of the chance it was that one guy trying to sneak another thread onto this board.
I think that's where a lot of these hang-ups come from. People end up associating a group of people with one person, and trying to pretend that anything related to what that one person is posting about is coming from that one person.
In many cases, the benefit of the doubt shouldn't be extended, or more importantly, it doesn't really matter if it's one or more people. If a hundred people wanted to start spamming CP on /tg/, or otherwise breaking the rules, that wouldn't make it any more or less right than if only one person did so.
In the case of KSBD, it's the unfortunate victim of exactly what this thread is trying to do. One person (or really, it could have been two, or ten, it doesn't actually matter) managed to taint something my mishandling how it was being posted, and that lead to it being treated as offtopic shitposting even when a person really was hoping to try and discuss the game.
