Yeah, I’d give him 5/10. Jumped the shark too early, which left him with nowhere to go. A good trolling would start slow and THEN explode into incoherent anger, and then refute the oppositions points with ad hominem attacks. This one just repeated the same ground over and over, so I’m docking him points for creativity.
On the other hand, he did convincingly drag several people down into the muck for a few days, so I can’t justify a low score.
