SilverProfit.net claims to be a site where you can make money for simply registering on its affilate sites.
the problem with silverprofit is its affiliate sites are illegal sites warez sites which are ran by SilverProfit's owner. I know this, because I know the person who runs the site.
they're using a WhoisGuard protection to keep the site's registration details from being public.
If you get payed by the site, they're using dirty money, which the administrator of SilverProfit gets from cracking credit cards and paypal accounts. (again i know this because i know the person..)

be careful of silverprofit. and any of the sites ran by them.
