CodeFixer Forum Spam

I’ve been getting a lot of spam comments lately, more than 10 per day. Usually they consist of the title
codefixer.com/forum/topic.asp?TOPIC_ID= and the body includes some random characters or something about various ringtones; cingular, elvis, hot, polyphonic etc.

If anyone has any idea why is this spam so agressive or how to minimize/get rid of it entirely, please let me know.

UPDATE: I’ve noticed a user, registered at my blog. Username is ralyjones25 with an email raly.jones@gmail.com so this IS a spam bot. Hope deleting this user will decrease spam flow.
