do something against fb fake accs

[deadlef]

hello,

is that possible to make something against fb fake accounts.

i think abaout something that only fb profiles who have more than xx friends can like...because there are too much they make fake acc and earn coins and then they never sign in ...or that the admin can check before the fb account when it looks like not fake acc than activate the pes account.

i want to have a serious site.
