You assume real people want to have their real identity verified. Probably many won't complain but I'm one of those who prefer not to end up in such place where my real identity is verified in order to be able to use services on the internet.
Not sure why you get downvoted, maybe bots problem is huge problem that should make users concerned? As for me, when facebook tried to force me to send scan of my ID over email in order to unblock my account I decided I benefit more by not unblocking it :) Facebook way was probably the wrong way to ensure your users are real human beings, but either way I like not to be verified when online.
