Why am I not doing it? I have more important things to do in my life than take part in those sorts of things. Sometimes I'll get involved in technical discussions but finding worthwhile stuff on here has gotten harder and harder. The last one was last year with segwit/big block discussions.
Did I say all his posts are "trolling"? I think not. His most "noteable" one, was him insulting someone and getting 50 points for it. He certainly does it in style though.
So why are you complaining then? Go on with your business if it's not affecting you in any way...
Also,
I bow to your forum trolling skills nullius.
That would imply that you're calling his posts trolling, and that's not true because he wouldn't be where he is if he was trolling. This is a forum.
