I think this might be one of the first times I didnt notice it, but just look through the comment history of https://news.ycombinator.com/threads?id=jackfranklyn , they all look the same.

Yeah on a second look GP might actually be on to something here. Jackfranklyn only makes top level comments, never dialogs with anyone, and I count at least 3 instances of "as someone who does this for a living" that are too seperated in scope to be plausibly realistic.
