Well, I was trying to figure out which category he fit into: sealioning, trolling, intensionally obtuse, emotionless pedant, naive internet sleuth, lazy internet sleuth, and even "completely serious fact-finder with no agenda". I think your "comedy" falls under "trolling" but I'd also be prepared for him being a completely serious fact-finder who truly believes that people are just lying. I've kind of lost interest because he's not contributing anything to the discussion.
