I've banned this guy, but PJ has offered me an idea - that the spammer might be related to - or the same as - the one(s) that have been showing up here so frequently.
I'm going to leave the topic up so we can more easily do some sleuthing, but I'll lock the thing so nobody - including him, of course, even though he's also banned - can do anything but look and laugh at him. I think maybe I'll go in and farkle with his URL so it won't lead to anything, either.
Sorry for the interruption, folks.
