What the F#@% ?

Has anyone else been getting fake comments on their blogs? They're not really comments from people but lousy advertisments for crap!! I've had three now pop up on some of my posts but I've deleted them cuz their stupid and shameless. Why are they advertising like that on a blog...as a comment? Like I'm going to believe someone REALLY wanted me to know this crap. I'll leave the last one I got so you can see for yourself. It's on the post for Found Ohsixhundredhours. See? Shameless and annoying! They must be stopped!!
