How handle user which posts numerous and often believable AI generated images?

I’ve tripped over a user who’s posted dozens, possibly hundreds (I cannot evaluate his mammal and bird images) of AI generated images. The images are of sufficiently high quality that experts (I am one) can be tricked at a hasty look.

How should I proceed? Can I report the user somehow?

Click the little “Flag” icon on one of the photos, and there is an option to report it as AI-generated content

I think you can use the “Flag as Inappropriate” button at the bottom of an individual record. But if it involves multiple records that are a problem, I’d contact staff via email.

Aaah. Thank you, will do. But he’s posted too many images to tag all, I’m mailing support.

This is fine to do, but it will also help to provide links to multiple images you believe have this issue. You could do this all on the one flag that you create and discussion can then focus on the pattern, not just the individual observation that you flag.

If we are talking about who I think, this then brings up scale. Individually flagging 200 300 400 or more observations is terribly tedious and time consuming.
