Oxylabs sells proxies for scrapers, I suppose you can use the socks-proxy as a VPN, and they claim to use Honeygain.

Honeygain is a platform where people sell their residential internet connection and bandwidth to these companies for money.

For comparison Honeygain pays someone 10 cents per GB, and Oxylabs sells it for $8/GB.

That takes buying low and selling high to a whole new level
