Spam a lot with his URL. Here is what I got from wordpress "Akismet, our anti-spam service located and alerted us to several instances of comment spam from your account (i.e. leaving comments on other blogs with the primary intention of directing traffic elsewhere). We have a zero tolerance policy for such behavior, and as such, you will need to refrain from this particular activity in the future. If it does continue, your blog will be permanently suspended" I used on IP for the spam and one for logging to wordpress.com.
