If we can't stop him from creating alts and post here how is taking this privilege from a few of his accounts going to work?
We're talking about a lunatic who had at least 55 accounts on this forum, right now nothing is going to stop him, even if you ban all active ones he will come up with 50 more, this is his way of enjoying life.

Don't get me wrong, I would love to see this happening but I also know that following the forum rules and the way theymos think about, let's call it freedom of speech nothing will change. And no,I'm not going to suggest ignore, the amount of spam and nonsense that comes from that guy can flood even Switzerland...and Nepal 

I would say lets' get rid of self-moderated topics in reputation, but...that will also end in a shitshow.
