This xbox robot comes in posting to the contact forms but not the blogs with his trackback links. Doesn't understand the error messages he gets or that he is wasting his time he just keeps hitting the contact form ever few days or so.
Should really be no trafic from inhoster.com since its not a ISP so its blocked.
Scrapers have also been reported on this domain.
Update: Trackback spam now poring in using a trackback agent.
Also recomend adding this IP to your servers IP ban.
