I don't think he's a troll, just aggressive and opinionated. 

Some of the funniest trolls are ones from a few years ago and who aren’t active anymore. 

I’m not sure if manyproofs would qualify as a troll, but his posts were hilarious to read.  I’m not sure if anyone could genuinely mangle the English language like he appeared to.

Fwdxlsh, mixan, kwukduck, and some other ones whose names I can’t remember also contributed some quality entertainment before they either got nuked or bored.  There was one (codishmumu) who kept saying she had a thigh gap.  Then there’s MPOE-PR from 2014 or so, who made some very intelligent but extremely biting posts.  They probably wouldn’t be considered strictly troll posts, but they were damn close.

We don’t have many trolls that are funny nowadays, just ones who rage against DT and the trust/merit systems—and thankfully that’s been on the decline recently.
