My first thought was this was an underhanded way to get more demographic data. I also don't like the potential privacy ramifications. What unintended places will those images end up? I don't use a public profile pic and I don't take selfies.
How this much different than the clubs that attempt to scan driver's licenses?
Hmmm... I guess since you don't use a public profile pic or take selfies this is a bad product idea. Or maybe, just maybe most people don't really care.
Maybe your point was that you won't use this particular product? Are you the person who also posts negative reviews on Yelp for restaurants you've never been to because you don't like that style of food?

At least there is a fall back to a pure barcode.
