Most people have such weird and illogical views on privacy. A website collecting face pictures without anything else is pretty useless. Walking in to a retail store owned by a company using facial recognition on a huge range of owned stores is a serious privacy issue.
And the bait on the hook is not a good indicator either - an appeal to a deep drive or insecurity in many people.
Obviously not determinative in itself ,but if I wanted to harvest a lot of faces in a hurry, that's exactly the sort of bait that I would use (I can hardly think of a better one off the top of my head).
Not useless at all, there are usually enough pictures of people on the internet with names, metadata, etc attached to immediately link and identify. Basically what Clearview does (did?). I would not be surprised if this was a data collection siphon.
I don't think this is a scam/data collection site (as others have recognized the researcher involved, etc.), but what would stop a random website from claiming it was "sponsored by the EU"?
