The IPs would get blocked.  If you had many IPs, chances are they would be from a small group of ranges and the entire ranges would get blocked.<p>For years the way I worked around the firewall from Shanghai was to run SOCKS proxy through an SSH tunnel to my U.S. server.  This works because its not advertised as such and China does not want to block all SSH/SSL traffic.<p>China is not trying to block everyone.  If you're well educated, tech-savvy, and have a credit card to rent a server outside China, you can get around the firewall.  Its that simple.  If you read Chinese, as most do in China, there are many avenues of (sometimes transient) data sources which carry just about everything you could imagine.  The information is out there, you just have to work a little harder to find it.   China, just like various interests that control U.S. media is going after the broad strokes.  In China they use the GFW, in the U.S., advertisers simply tell the top 4 media companies to not talk about certain things or else their ad money will dry up.  The results as to what the general populous know are similar in my opinion.
