There are people somewhere who scour the blogs posting comments containing links to various websites. The object, I think, is to boost their scores on the search engines but I'm not sure this actually works. I imagine that these people are being paid to post comments.
I get about 20 of these spam comments per day. Since I moderate comments they never get posted and you, dear readers, never see them. The Blogger spam catcher puts most of them in the spam bucket.
So what's the point? The people posting these comments are wasting their time, and wasting my time as well. Is that the goal? I don't get it.
