Your shit out of luck
They got more spambots than people in china, at least it seems that way to anyone running a server who bothers to track the ip addresses. As a result, many, many websites just simply put huge IP block bans on China, Russia and Ukraine.
The second group of servers to block are any kind of proxy... Again these are crawling with spammers, hackers and other internet low lifes.
So a whole bunch of Data Centers are blocked.
Of interest to truthers, most of the spam e-mail addresses are Google Mail.
The worst datacenter would be Amazon's Cloud
The answer is to get a nice clean IP address from a server not located anywhere near the above.
