The big problem I see with this, Squill, is that once you go down the road of quelling topics -- like bringing up personal issues with consoles, or developers, or whatnot -- you also remove the basic substance that makes the forums interesting.
If no one argued over opinions, and everyone found all consoles pleasant, and decided not to comment on the failings of said consoles, or developers, etc., then all of a sudden they can't make any interesting statements about future console sales, or game sales, etc. either.
Every opinion that becomes a ban rule makes interesting reasoning, and hence interesting posts, less so. Universally stating that all such harsh opinions are untrue, or unworthy to be included in the forum discussion, is too much control in an environment that thrives on freedom.
