The IP thing is interesting, I was trying to make this CSGO bot one time to scrape steam's prices and there are proxy services out there you rent, tried at least one and it was blocked by steam. So I wonder if people buy real IPs.
you can get paid about $0.10/GB in cryptocurrency (at a few GB per month) to run one on your PC. Apparently they also just buy actual connections sometimes. It's not even unethical - it's just two groups of equally bad businesspeople trying to spend money to block the other one.
