Your mitigations are so bad, you must know that they are almost useless. No website has ever kept up with spam by individually checking every complaint, and you would only stop people after they've already recorded large amounts of output from a stolen voice.

On the other hand, as you also know, you could easily put a much stronger safeguard on by making people say a short prepared statement and only clone voices who have said that statement. You do not appear to have done that. Why not, except it would make it harder to voice steal?
