> Assume a group builds a social network just like Twitter, but with verified users, actually verified
Facebook tried this and as far as I can remember it was found illegal in Europe for a social network to require people to upload their ID, or use their real names.
I am not saying upload something and have the social network verify the identity. Maybe something like VideoIdent/IDnow could work. Basically: Get a license to comment, the way you get a license to drive.
I mean, this should not replace Twitter, but offer a less harassing environment.
