Hi!
Just wanted to share a website that I use to access those blocked (youtube mainly) and has been fairly reliable.
www.kproxy.comA few things to note:
-The server overloads from time to time, but as long as you keep trying, you should be able to use it fairly quickly
-Depending on your browser, you may get a pop-up ad or two. Nothing too major in my experience
-Youtube comes up in French. There'll be an option for you to change to English, you have to press the button that says "Annular", whatever that means, and that'll fix it for that browsing session.
Most of the other proxies that I had used, such as anonymouse, ibypass, and iamunblocked, have been blocked, so if you guys know of others, then hope you can share!
