I earn some fast cash from proxies with adsense but proxies need fast and reliable servers or your vistitors will run away when they found that your proxy is offline. Now I use x Proxy Host due to its fast servers.

x Proxy Host is becoming a recognized provider of PHP proxy hosting. Their service is specialized for web sites that use PHProxy, Glype, Zelune, Surrogafier and other similar PHP applications. They operate on an extremely fast network with high performance server hardware. The uptime of their client’s web sites are a top priority and they have very effective tech support. If you are a beginner they will help you with your first proxy site. All accounts come with cPanel, country blockers and IP blockers.
