Unfortunately the cards are stacked against you. Websites have a financial interest in not taking down your content, or really anyone's, because they know that ads can stil run on it and only big studios will sue.

I think, in the future, with AI facial recognition and massive databases, there will be professional services catering to both amateur sleuths (who want to see if someone they know ever appeared online) and former content creators (who want to disappear from the adult cyberspace).

By the book, though, you do absolutely have the right to take down content that was not posted with a license agreement. I wish you the best, and I really do hope that you succeed. But I would just offer my two cents: there is no real erasure. Not really. But there is also no shame in having overcome the past. I totally understand wanting to remove this stuff from your public persona. But you'll never completely remove it, and that's nothing to be ashamed of in my opinion. You're not doing it today; that's what counts.
