Someone impersonating me

I’m a smaller creator but my videos have gained a lot of traction recently and that, of course, led to some accounts posting my videos and pretending to be a “backup”. I don’t really care about it that much, but what I do care about is they put my personal email in their bio, which I don’t give out to the public, and now, I’m getting random emails from brands and stuff which is super annoying. I’ve reported them to YouTube multiple times, specifically siting the use of my personal email, but they don’t care. Is there anything I can do or is it a lost cause?
