There's undoubtedly photo manipulation going on & some use of AI in stills (eg she posted a pic of her with Johnny Sins like a bunch of girls did a few months back). But the videos are genuine as far as I can tell. I'm no expert, but if you look at the way she interacts with objects (sex toys, clothing, bedsheets etc) there's none of the weirdness you see with AI.
Of course I could be wrong - like I say I don't know a lot about the topic. But these allegations have been made before & I have yet to see any firm evidence.
