Because of the multiple threads used in the account creation process you do need proxies to avoid your IP getting banned within the first few minutes of starting the account creation process. Using a proxy hides you IP address and uses the proxy IP in the account creation process.
We recommend two proxy services for use with VSA.
1] http://squidproxies.com– these are private proxies and are highly recommended.
2] BuyProxies.org – Semi private proxies. These are shared proxies and are less expensive but also work very well
