Edit: I'm glad this thread exists. The shitposting problem is like the 900 pound gorilla in the room that no one acknowledges. And no one acknowledges that campaign managers aren't doing much to keep these posters out of campaigns anymore.
Edit edit: Those shitposters who aren't in sig campaigns: I think a lot of them are account farmers, just posting to rank up so that they can sell those accounts. I don't have proof, just a strong suspicion.
I also have respect for campaign managers like Yahoo62278, Lutpin, Lauda, and Edwardard and I realize they have bosses to please too. Even Secondstrade was getting good at not accepting shitposters toward the end. It's just lately I've seen tons of shitposters wearing signatures from SMAS campaigns. I don't think some of them take that seriously anymore, else they would never accept some of these people.
