The way I see it, it's one of two things:
1. He must be from Hawaii and need a fix. He's half a bubble off anyway, so this should be considered a normal way of saying he's hungry and wants SPAM.
2. He's still cruising old posts and must think he's doing a community service of alerting us and the mods of posts he considers to be SPAM. On the planet he comes from, introductions are SPAM.
There is also the outside chance that he is just a whack job displaying his normal behavior. If that's the case, he fits right in with so many others here. Thank God I'm normal.
