I've often thought about this. Nice pics on the profile, and then a verification pic that looks like they have just been dragged out of bed. I'm not talking about the real con artists here, but those WGs that actually look nice with a bit of effort. They know (OK some of them are really stupid, so most know) that the verification pic will eventually be hacked and will be generally available.
To my mind, a profile that is backed up with a tidy (by which I mean a little make-up, brushed hair, nice but normal clothes, like she might go to a civvy job) verification pic is a real selling point. Suggests the girl is honest and you might get what you expect. A little effort, please.
