Ok, I'll be a bit more specific, banning businesses and the trade of proxies that are purposefully marked as residential, in order to evade firewall blocks, and even to evade proxy blocks.
You gotta draw the line in the sand somewhere, VPNs are already morally dubious, but if you ban the most shady of VPNs, residential proxies, then you can at least guarantee service providers the right to deny service to proxy users, while allowing proxy users to use the proxy everwhere they are welcome in.
yah, but how else am I going to create millions of youtube accounts to spam sex bot ads >:(
on a more serious note, it's just not really possible since most residential proxy sites are botnets :)
But the botnets don't use VPNs, they use IoT devices owned by people who don't even know there's a computer inside. It seems like you just don't like the idea of VPNs in general and are using an unrelated attack to argue for deprivatizing (And thus, surveilling) the citizenry.
