He wasn't banned simply because of the way he felt about the various projects. He was banned because he was consistently going into those same projects and berating the posters for continuing their projects, or posting them in the Preservation forum.
It's one thing to make your feelings known - it's another to do so sereval times a week, for the sole purpose of shouting people out of a forum. DB wanted the forums run the way he wanted, and the LD transfers to be done the way he wanted, regardless of what anyone else wanted. His constant attacks, after several warnings, are what got him banned.
