I am reasonably confident calling it flatly false at this point, given the absurd amount of fine-detail combing over of Zoe Quinn's life done by her harrassers that's still never come up with anything real to present.

It's neither of those things. It's not the accusation that was made at all; the original claim was that she slept with a reviewer who gave her game positive coverage. The entire gaming press debunked this based on the technicality that it wasn't actually a review, but that wasn't the claim that was going around. Supposedly they also weren't technically in that kind of relationship until shortly after the press coverage, but that went down less well as a counter-argument for obvious reasons.

(This also wasn't the focus of the original blog post at all. To cut a decades-long story short, the reason that particular aspect caught people's attention was because there were a whole bunch of people who already very strongly distrusted the entire gaming press for reasons entirely unrelated to women. Then Reddit started shadowbanning anyone who mentioned the journo's name, hosters were pressured to shut down sites which covered it, the entire gaming press declared gamers as a whole misogynistic scum over it, and every escalation fanned the flames more in typical Streisand-effect fashion. In fact I don't think it was even mentioned in the blog at all, but I could be wrong.)
