I think he's trolling
From my experience, I've noticed that
actual trolls usually try to be a bit more offensive. If Johnny Blockhead is indeed trolling, then it's an instance of the "DURHAHUR I'M STUPID. JK JOKES ON THEM I GOT THEM GOOD," kind of "trolling" that just makes the person in question appear to be even stupider. Of course, that isn't to say that any kind of trolling can make one look intelligent.
I have absolutely no faith in Johnny, and believe that his posts were sincere; after all, they seem like something a 12 year old make on a whim.
