The use of proxy is allowed but if you use a proxy to enter your adsense account your account will be disabled. It has been seen lately that you can use proxies for logins, but sign up must be from a real computer. Proxies like hidemyass, armyproxy, schoolproxy, etc, can be used after signup.

Be careful.
