spammer going to priovate messages

I just got an email that smiley tried to private message me but my inbox was filled. I cleared out all my messages and then jump on the forum to find out smiley was a bad guy, and he's jumping unto the private message board. Uh oh.
Send us a link in the mod section and we will zap him (sorry guys all I can do is delete his account)
Can you delete my account for me. The knives that I am selling are not what the members of this site want.
Thanks for your help,
