You cannot use a proxy when connecting to the freesites. This will cause you to be put on hold or to go red. Using a proxy is where data from your computer is sent to a "proxy server" before being sent to the server you are connecting to. It is essentially a way to hide your IP address or computer to the server (website). A proxy will change a persons IP address. This enables people to sign up on the sites multiple times (can only sign up on each site once) and then causing that person to go red. Some internet service providers (ISP) use proxy servers with their services (including, but not limited to, AOL, Earthlink, Netscape, DirectPC, and some DSL providers). You are urged not to use these ISPs when you are completing offers. In most cases you are put on hold immediately for using AOL internet.
