Dude if you think that someone might scrape your finger print from a random image post, recreate a physical model of it, hunt you down in real life, and steal your phone to unlock it… You probably should be seeking political asylum because you’re being hunted down by the Kremlin or a similar entity.

My point being, unless you’re wanted by a governmental power, a photo with fingerprints is probably not a real risk. Gotta make a realistic threat model, otherwise there’s no way to tell what’s reasonable privacy considerations vs. paranoia.

Not sure where you’re located, but at least in the USA it’s definitely illegal for an employer to discriminate against a medical diagnosis like that. They aren’t even allowed to ask you private medical questions during the hiring process.
