Stop That!

I guess I'm going to have to put 'Comment Moderation' on my blogs. Someone's 'Bot' has picked on my posts that mention any word pertaining to the medical field, and that is when the bot drops off a short but inane comment with a link to a software site that sells automated phone service to doctors. I sent them an email, asking them to knock it off, but it was ignored and I found another one this morning.
