A new user has shown up with what appears to be a "I've never seen this one before, but I know spam when I smell it" username, rather than spamming links in answers. I can't recall any mention of "not spamming" in the username rules - I can't even recall what rules there even are for choosing a username. But I know spam when I smell it. Having commented without any effect, is there a process for flagging such things, or is this a loophole that will have to await a rules change to deal with?
Looking at the user's profile and questions they are asking on other sites, along with the web page they are linking to, I believe this falls short of the typical spam we would remove. The url doesn't appear to be the focus of any of their questions, but more of a personal reference, and the content of their questions aren't stepping over the line of the self promotion policy. To create a policy about url's in a user name, I believe that needs to move up to the SE meta site.
