People with his (her?) attitude tend to make the forums more fun!
I'm fairly sure that's not an unanimous feeling. It seemed most people were annoyed at him.
He only got banned after repeating his behaviour, even after several people tried to talk sense into him. He's not going to change, not from our feedback or meddling. It's gonna take something else, maybe time, maybe someone he's close to talking sense into him. Until then, I don't think having someone making threads to say we're wrong to criticize him is good for the community.
