OKCupid and other services already have this feature implemented. With the absolutely rampant abuse of catfish on Grindr, why why why is this not already a feature? It should be a REQUIREMENT of creating a profile. Facial recognition on signup and you can't post any pictures that don't match the verified face. The pictures don't have to show a face but if they do the verified face needs to be on them.

YOU CAN STOP CATFISH TODAY. The tech is available. DO IT. DO IT NOW.
