Be very careful with Hardcore Clicks and X Bucks!!!
 

Dear adult webmasters and webmistresses, if you want to
be an affiliate of http://www.hardcoreclicks.com and
http://www.xbucks.com , be very careful! Although, the slogan
of Hardcore Clicks is "honest to the last penny", they didn't send
my $420 payouts. And X Bucks didn't send my $120.
Also no responding to my mails. Attention!!!

Thanks for the heads up. :thumbsup
