I haven't run the numbers, but a huge percentage of websites are inaccessible through a VPN, and it's a PITA for daily use.
I've even tried to enter a restaurant menu by scanning the QR code and it wouldn't load (no error message), because I was using a VPN.
I would imagine TOR is blocked even more than VPNs.
What if the web worked through BTC/LN, and every page load charged a very very small amount automatically?
Wouldn't that eliminate spam without any burden to normal users?
