What if someone claims to feel violated by an image of a person that looks totally different: different skin color, different build, different facial structure, etc?

Then they'll try to convince the authorities that the image is of them, and presumably mostly fail although in some cases they may succeed. (If you're worried about something like the US DMCA, that's almost certainly not going to be the proposal; the UK has a number of existing 48 hour takedown policies, and they all involve orders from the authorities rather than self-certified requests from random third parties.)

How will the government determine which images fail or succeed this claim?
