Providers asking for photos

I was just asked to provide a photo with me holding 2 fingers up. Seems like a trap to get you with intent prior to meeting, but maybe just my tin foil hat.

I understand the provider maybe looking out for her safety, but the recent bust has me leery on things like that. Any thoughts in that area? I mean i could just find a pic off the internet easy enouhg to send.
Yeah I am torn on this as well... I've dsent a pic once before and it turned out fine, but I try to not have to and don't know that I would again....
I have done the same thing. I usually ask for one in return
