Anyone engaging in legally questionable activity who didn't already consider this attack vector and take it seriously simply haven't been paying attention and have bad OPSEC. The possibility of this kind of attack has always been mathematically possible and it doesn't take machine learning or computer vision to do it. It boils down to basic linear transformation.
