Possible fake user profiles

I've stumbled across a couple of profiles that feel fake: 

audrey_jean (ur211905850) 82 reviews, all in the past two days

Arielleth (ur42901925) 213 reviews, all in the past 20 days

The reviews don't contain specific details about the movie, and seem AI-generated.

The titles themselves seem picked at random - a bunch of movies beginning with the same letter, then switch to a different letter and repeat.

(Side note: is there a way to flag fake profiles, aside from writing in the forum? I think that the AI-generated reviews is a problem that will only get worse.)
