Spam in "about me"

I just had a look at some of the spam-flags I raised some time ago. In the course of this I stumbled upon this userprofile: The account has no (undeleted) posts and its "about me" contains 100% pure and untainted spam. I know it's rather unlikely anyone will stumble over this profile (if it wasn't for this post) and the userprofile isn't exactly required to be on topic. But shouldn't the account still be deleted - or at least have its "about me" removed?
