Stop going there if the forum bothers you.
I read a few posts over there, I did not see one complaint about users being banned for no reason. To be honest, they seemed like perfectly normal discussions, which is odd with a forum that allows anonymous posting.
This is the reason Nick asked for explicit links to posts with these complaints or posts with terms of use agreement breaches. It is not up to him, or us, the volunteer moderators here, to go investigate your claim. You have to show proof before anything will be done. Posts on other forums are no better than anonymous e-mails. There needs to be physical proof of wrongdoing. Heresay won't stand up here any better than it would in a courtroom.
If there are no terms of use agreement breaches, there is no reason to terminate the forum or remove anyone's priveledges (that cannot be done anyway). The owner of the forum can do with it as they please, as long as they don't breach the terms of use.
