Let's say china for example doesn't allow it's users to access certain sites. I think google might be included. The use of proxies come into play here. Yet think about this. Before you can send info to the proxy it has to go through the isp. Since the isp in china should be under government control won't they be able to see what the poster is receiving and sending to and from the proxy server? Wouldn't the user who's using an invisible proxy still be caught? I'm a green horn here. Who knows there's probably a whole ton of info going to and fro from a huge country like china that it's impossible to even check by this way. Let's say your in china maybe for work. You want to access a forbidden site, how do u ensure that you cannot be found out? Is data sent to the isp encrypted?
