Spamming, definitely.  He is also trolling, albeit in an unusual way.

I've reported quite a few of his posts, but not in the threads he's created.  But now he's starting multiple threads which are (I think; I have him on ignore) basically the same anti-DT crusading that he's been doing for months with no results.  I do think it's about time he got banned.  I'm just tired of seeing either his posts or his threads pop up on my unread posts feed. 

He's so annoying, even the ignore function isn't enough.
