At least those bots are easy to block though. I run a niche stats website for an esport and I have no idea why there's loads of residential trawlers/botnets with 10k+ IPs trying to get that data - most of what they scrape is directly available from Valve's APIs.

Probably as simple as the fact that there are unmetered residential proxy plans, which means once you're already paying for one, there's no reason not to use it for everything.
