at a track day, blue painter's tape works fine. Otherwise you had your chance.

If a car is photographed in public, you're also SOL as you have no expectation of privacy in public.

If you're the photographer and take your own picture, of your car on your property, with the plate on and post it online you're taking an unecessary risk for no good reason.

and let just add, all databases have been hacked. Public, corporate and especially govt.
