Well, it's schizophrenic outsider art, so it's hard to explain what the message is. To me, it seems like he's saying that Nick, Dick and Ralph are all grifters. And Dick and Ralph have made their money mocking other people lolcows and yet they're vulnerable to the same mockery. Same with Josh. Nick's 'sin' was getting a bunch of people hyped about Kick Vick, losing the case and then just carrying on the grift.
And he's got a point. I think he's just trolling himself though and probably doesn't really take any of this seriously. However, the weird thing is that other people are picking up on this, and they might well take it seriously.
An absolute tsunami of trolls is going to descend on the people he's mocking, and it is glorious.
