More Bots....

Ah, here we go: a quote (from here) on the type of bot that user is as well as a user that just joined (as of this post)

Alternatively, the spam links are posted in the user's signature, in which case the spambot will never post. The link sits quietly in the signature field, where it is more likely to be harvested by search engine spiders than discovered by forum administrators and moderators.

so just as annoying as the other variety of spambots.
now if you'll excuse me *goes to member list to flush out the rest of these spam bots*
