I agree with Bret, but "the benefit of remembering faces" is that it 
makes  large scale fraud much more difficult, because the creation 
of multiple identities cannot be programmed - at least I assume it.

Pindar identified ("Are you real?"). Why isn't it also possible for a single
user to create multiple fraudulent accounts with Realuser?
