Why can not I write on the walls of people using Facebook through an anonymous proxy?

My work has blocked on Facebook, as well that access to the site through proxy sites and anonymous as www.thespacesurf.com www.zend2.com but I am not able to use many features such as writing on the walls of people. I can leave comments on photos and some other things though. Does anyone know why and how to fix it? Thanks

You Talk to your network administrator at work an tell them you are having trouble using Facebook and maybe they will fix it! : D
