Well, the hacker got back in and left his fingerprint on the site. Whee. So I dumped the site and reinstalled, restored and reconfigured. I took the opportunity to replace some of the Facebook integration tools and remove some underutilized plugins. Time will tell if the site stays clean or not.
Looks like some douche-bag hacked into the blog. Fortunately I think I caught it early enough to limit damage and restore the posts. Don’t people have anything better to do with their time?
