Just saying that I can't think of one banning that didn't start with a person differing with rebbivs point of view.
Personally, I'm fine with his postings. But it shouldn't be illegal to differ, which I feel it is sometimes.
The ban a year ago was for a poster baiting, swearing at many regular posters including mods.
Early on here and at the previous forum that Monster started, there were at least 2 or 3 posters who just came on to mess with posters much the same style.
So in answer to your assumption there have been bans of varying lengths that had nothing to do with Rebbiv.
