This has always confused me... how do companies like ****** and the like detect proxies even though they aren't detected as a proxy on sites like whatismyipaddress.com? They claim to have a "daily" updated proxy list, but I haven't a clue where they get it from. I've searched to no avail... Seems like an excellent way to protect against affiliate fraud too. Any idea where they're pulling it from? Because its a very accurate list.
