The OP said his posts were on-topic, but LOL. I had a blog entry on fixing my car and got a comment about dog hygiene or something like that. I was like WTF? *shrug* At the time I didn't even own a dog, so no clue what the guy was thinking, as if I would even consider allowing a post about pet care in an automotive topic.... then again, I think it was a bot. I also got a similar comment in one of my pagan/magick blogs. (askimet much?)
