Acting in such a way that is disruptive, and that fails to contribute to a thread that would be otherwise succeed as a place for serious discussion is not allowed. Acting consistently in this manner will lead to a warning, then the removal of your posts and related in that thread, then a ban. Should a ban be given, evidence of disruptive and clearly troll-like behaviour will be shown, to ensure this rule cannot be abused by staff who may dislike a member for personal reasons.
I dunno, musing. Also, the ban would be temporary, I picture, at first.
