A comment I don't understand

I really enjoy writing this blog and reading the comments made. But there is one set of comments I just don't get.

The woodworkers that say how they were surfing and found my blog. Without exception the format of their response is identical, though the links they put in are different. This leads me to think it is some kind of a program that crawls the web and post comments in blogsites. That is lame. Why would anyone write a program to make annonymous comments and then to return to that site many, many times. I would like to turn that switch off, but still allow comments from 'annonymous' readers.

In the mean time, I will just see if there is a way to delete their comment/ads.

On to a more pleasant topic next blog. I promise. ;-)
