I got hacked. It was pointless and ugly. I screwed up my database before I thought to back it up. Restoring it was more hassle than I cared to endure for the blog anyway. I hope WordPress 2.0 is more secure. I do plan to back this one up.
I feel kind of like someone had spray painted the front of my house for no good reason. At least repairing this damage is less expensive than getting rid of graffiti.
