Wow power leveling

Wow, I very rarely get spam that survives “Bad Behavior” and “JS Spamblock”, but this morning I had 14 spams on 3 out of 6 WP installations on the same server all of Wow Power Leveling (a paid game site like it seems) with all kinds of compliments that didn’t really fit the content of the posts. It seems like somebody found a way to avoid my plugins.
