Well, let's be honest here many peoples' identities are worthless. If you're living in a drain in Lesotho it's not as if anyone can do much with it, that's if you can afford documents at all.
A fine demonstration was the joke KYC on here on April Fool's day. In the joke application thread there were a suspiciously large number of genuine-looking selfies.
I'm not going to hand stuff over to any random site, but, unfashionable as it might be to say, I don't really give a shit if a hack has those documents away. I own nothing. I have no credit. I will never, ever have any credit. If someone signs me up for the Foreign Legion without my knowledge I'd probably join it anyway for something to do.
