The owner of this sit here, http://www.youradsenseprofits.com Keeps spamming my site http://www.blogengage.com now what he's doing is taking other domain names he owns I guess and forwarding them to that site seeing that site is already banned! The last one I just banned was http://www.automatic-content.com So today he has submitted like 10 times and over the last month maybe 100! I did a whois and requested he stop but no luck! Any suggestions on what my next step is?
IMO this isn't enough info to give full advice but check your access_log (!!!) to see what referrer he uses each time what agent he uses each time what IP he uses to access/enter your site each time if one of above is identical for all submissions, then you have a rather easy job to block either the referrer agent ( unless its a mozilla or IE ) IP using .htaccess if you require registering before submission maybe you can change your register-defaults to require admin verification before submissions are accepted or if he uses same email - block email
