So a couple months ago I wrote about my new car. I was trying to make a point about some of the massive testing that must go into the development of ever-more-advanced vehicles. I've now had 11 comments on that one post, most of them using key words about the make and model of the car, and practically none of them writing about testing.
Who are these people? As it turns out, they're all just hot-linking back to various auto dealerships and car parts stores. Who has time to do that? I wonder if there's some small company out in the middle of nowhere that hires a bunch of people to write comments all day long and post them to different sites in an attempt to game the system by increasing links to their sites. Or they could contract the work out on a "per post" basis to hard-up college students looking to make a few bucks. The student downloads some software that trolls the internet for them, looking for blog posts, forums, etc. that relate to a certain customer, and then the student is paid a couple bucks for every post/comment/etc. that they write. What a world.
Anyway, I'm just going to delete them all.
Here's a Google article about this.
