There's no evidence that any sort of unethical activity happened regarding Quinn promoting her game. There's no evidence she slept with anyone, for any reason. There's no evidence she paid for good reviews, with sex or with any other currency. There's no journalistic conspiracy regarding her.

Does games journalism suck? Sure. It barely qualifies as journalism. But regurgitating ad copy is not a crime, unethical or unusual. Professional film reviewers write actual ad copy for blurbs on the poster, TV ads, home video releases et al in their reviews.

The idea that she faked personal harassment is a laughable conspiracy itself. There is literally a 450 page thread on another forum I read devoted to the idea that Quinn and Anita Sarkeesian are cult leaders who use indie games festivals as sexual brainwashing centers to molest vulnerable gamers into their ideology and that federal agents should form a task force to arrest or kill them. Of course Zoe Quinn is being harassed. The entire "scandal" originated from her ex-boyfriend launching a series of public accusations against her. Calling your ex-girlfriend a whore in public is harassment, friends.
