I'm not sure if a poster can have their thread starting privileges revoked or not. At a site where I was an administrator we could do this. It pissed some members off, but for most it was a way to shut them the fuck up.
For shithead straight it would possibly do a couple of things. If his thread started privileges were revoked, we could only hope and pray that he would have plenty of sharp objects on hand, which would put this miserable asswipe out of his misery.
Or if they weren't revoked we could just quit answering his postings, which could possibly be worse. As he sits there thinking he's agitating us, no doubt he logs on several times a day seeing if he could get a rise out of anybody, and no replies would piss him off to many degrees. So, in this context, I say no, let the miserable asswipe keep making a bigger fool of himself for all to see.
You see, in this day of fake news, even he knows his signature is a lie, and I don't believe that he believes everything he posts. He's an idiot with a huge need for attention, be it good attention or bad attention, it's in his DNA to look and act like a complete fool.
