Out of interest years ago, I spend $20 on a few different gigs that offered link building, the results were actually amazing. (Not in a good way) They usually offer to post links for a couple of days, and sure enough, right on the dot, you can see traffic flowing in, once the period is over, it suddenly stops. Of course all traffic came from AWS or Google Cloud. I confronted one of the guys with the data I saw, he then decided to just keep one of his virtual machines up, and drive fake traffic to my site for months. I did have some good results with some tedious data scraping tasks. But you have to explicitly tell them what you want, and in what format.
