I think the issue here is the between consenting adults part, deepfakes in this instance are probably not between consenting adults. I also think it's important to think about the reality of how this likely plays out. If someone deepfakes me and faps and I never find out and they never tell anyone, it would be quite hard for there to be action. So if someone is deepfaking you and you know about it, there must be a logical path there, and none of them look good for the deepfaker. Can't say I know where I land on the issue, and I've thought about it for days and hours.
