That one is actually Chinese, rather than Korean: roleplayerguild.com/users/dgsdegsdfhds
@Hank: Looking at the userlist, I noticed there are a few new nuked users with no posts, however it looks like users do retain their post counts upon being nuked - how does this work? Did they use statuses/Bio/VMs? I wouldn't quite put it past genuine users to choose "nonsense" names like that, as much as I've seen a number of people with less "human" names than most of the KoreaBots.
Post count isn't impacted by hiding posts.
EDIT: Oh, I finally understand your question. Spam bots are easily recognised because their usernames are identical to their email adresses, usually hosted on some kind of weird, obscure free webmail service. I just nuke all of them, posts or no posts.
