I don't think people should be banned for lack of positive contribution. The only grounds I think someone should be banned is for actually taking away from the forums. By attacking users, bad language, spam, etc.
From all the posts I've seen of LVHCM, they have all been pretty negative. I don't know if they are bad enough to require banning, but that's not my decision.
I just wanted to post to say I don't think someone should get banned because they aren't adding anything of great value to the forum. They should only be banned if they are doing the forum damage.
