A proxy would help if the block was working the otherway, a site blocking you based on your ip. In your case you IT dept have put Facebook on a block list your end. Proxies are not dangerous, just ignorant people too stupid to discern between BS and the real deal are dangerous.
Why don't you give http://turv.info a try as it's brand new in only the last few hours, or if you need a secure ssl proxy then try https://subpr.com instead. You know you can trust both sites as they are part of the Vtunnel network :) If you use the shortcut to Facebook from the homepage then you shouldn't have any problems using Facebook at all, plus there are shortcuts to Twitter and instant messengers as well. Enjoy!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
