Most proxies I've tried such as hidemyass have been blocked too, do you think this would be too?
The reason that one works at my school is because it's my own custom website, so it's not on the blacklist. Some schools use more intelligent filters that scan for keywords like proxy, in which case you're still likely to be forgeted with that one. But if your school is like mine and operates on a blacklist, that
should work.
