I don't know much about the state of the art in image recognition but does it really seem plausible? The picture of him holding the beer is not super high quality, he has a different expression, a slightly different haircut and he appears quite a bit older. You can't even see his distinctive freckles. The idea that you could just scan random images of people online and find him that way is wild to me, tuning the network not to miss it but also not to report millions of false positives seems like a very high bar.

It's pretty creepy if we're already at the point where any random people can trace you online using apparently unrelated low quality photos.
