How to get rid of these submitters?

• March 14, 2009

Oke here my problem for a couple of days i get the strangest submits at my linksite!
Example:
url:http://cmfaixgtjnux.com/
submitters name: uwjpthvj
email:fvyezr@mrlfrm.com
ip:208.85.181.35
in januar this year i got realy 100s a day of submits like that, everytime strange urls, strange emails, but most of the time same ip, i did manage to block the ips from the others, but now all the submits have ip: 208.85.181.35……and ven i have blocked it, it still comes thru my submitpage…..by 100s again, i have tried to search but cant find any trace on the domains or emails….!
So any advice how to stop them is welcome!
