Blog Comment Spam is a Thing?

Amazing — this blog has been in existence for less than 24 hours and I’m averaging about 1 spam comment per hour!

These are all replies to my first post, and all of them are clearly computer-generated, and not responsive to the post content.

I’ve naturally marked them as spam, but other than automated spam filtering I’m mostly curious as to what’s the point. Are these <people> just trying to get links into Google’s search database, or is there some more nefarious intentipon? None, so far, have asked me to click on links.
