Reasonable, but to the extent the person feels their privacy is being violated it's hard to expect them to voluntarily self-violate it further (and be accused of having shopped the screenshot etc). Other discussion in the thread suggest both that Snapchat's in-app AI validates the claim, and that the website of the advertiser is exactly the sort of sketchy degree mill that you would expect to use such techniques.
It might be an elaborate prank perpetrated by multiple people working in concert, but 'tech company known for violating privacy violates privacy again' seems at least equally economical.
