Sorry, I only have Moderator access on the Hinterlands thread so I can't remove the rest of the spam posts or delete/block the user/user IP.
WOTE, might institute some sort of process whereby mods have to approve the first two posts of a new user before they can be allowed to post freely? It's something we do on Unseen Servant. I'm pretty sure it's a feature of phpBB forum code and not something our site admin stitched together with extra coding.
