My Blog is getting trashed.

Last night I found this pill on the floor. I didn't recognize it so I did these Google searches to find out. Turns out it was an old tramadol (I used to take em for my back)...Anyhow, today I have 20 comments on one of my old posts. (Luckily it is an old one, and not on the front page.) The comments are from "Vicodin", and "Hydrocodone", etc. Weird. How did they find my blog? I might start screening...except I get so few comments. Anyhow, I might just quit this and go to Facebook, or MySpace.
