Hi,
Nitroglobal is a client/server based accelerator system based out of Singapore, and we have had large numbers of people from the UAE and other local areas using the system as an anonymous proxy.
Because it is not a standard proxy and requries a client to be installed, it cannot be tested using traditional proxy testers and therefore is less likely to be banned.
Anyone can get a free trial of the system by visiting http://download.nitroglobal.com and registering with your e-mail.
Rgds
Paul
