On the other hand, I think one protection against this particular scenario are the people who make their money using their likeness. Like, what if in that particular situation, Taylor Swift's dad (pick any celebrity) was the one browsing the internet. He just got served an advertisement with not just his daughter's face on it, but an ad with Taylor Swift's unlicensed likeness, where that likeness in most other situations is worth many millions of dollars. For some tiny group that's below-board anyway with hacking people's social media accounts, I guess maybe there's not much you could do. But for any social media site or other platform, I imagine that IP lawyers trying to protect their client's likeness would descend in packs, which is a probably a genuine deterrent to a group considering implementing something like this.
