I've asked all my friends and they wont let me refer them and i've advertised on fb and twitter with no luck , so how do i get referrals?

create your own blog to promot your sponsor link........on blog tell your visitors how to make money with clixsense
and give them your sponsor link........

to get visitors to your blog try Traffic exchange site or post your blog address on various classified sites

use youtube etc
