@infamousbelgian what if we added a new field to the user profile that would list alt accounts and dealt with this client side. Like when I followed someone I could follow just that one account or I could follow all their alt accounts too. When I looked at comment history I could see comments by just that one account or by all alt accounts ect. It would verify that the person wasn't lying because the alts would have to be listed on both accounts to show mutual account controll.. Perhaps each alt could also have a short description.

@infamousbelgian you can move telefone numbers between providers, indeed this is dictated by law. but you can't do the same with email...
