If you think this comment was not written by the account holder or that account sales are occurring, please do as asked by the guidelines in such cases and contact the mods to report that, instead of posting about it in a discussion.
I wouldn't know if account sales was occurring, my first thought was that they sincerely wanted to have AI critique this article and post here. I don't think it is a good enough reason for me personally to flag.
I think if someone was trying to use AI to farm they wouldn't post these types of critiques, but something safer rather.
But I did wanted to see what their reasoning for posting those AI critiques was, and they answered, so I got my curiousity satisifed to an extent.
Irrelevant; “If you're worried about abuse, email [email protected] and we'll look at the data.” and especially “Don't feed egregious comments by replying; flag them instead.” both apply.
