This is silly and slightly funny spam, but can't you guys block or remove Wacewrach before they keep posting? It's not the worse thing in my inbox, but I see no point in letting them go on doing it.
It's in my email inbox, but only because of the postings on here, Padraic. I have a subscription to "Members helping members - Administrator Support" so I've gotten the messages that you've seen, but nothing more, Wacewrach hasn't spammed me directly. I'm just a little surprised you haven't block or deleted him/her already. I think you nailed it when you said it was some kind of "message spam."
