So I accidentally read one of lots of viagra spams I receive each day and noticed this link: http://verstraeteinmuebles.com/wp-admin/css/2dt45h.php When you click on it you are redirected to a site selling viagra (http://medicineprescriptionmedicare.com). I guess that the owner of this site has no idea that something like this is there. It seems that spammers hack sites and put there redirecting files like this one to accomplish their filthy intentions.
