my point (and i think that of the person you originally replied to) was that if you have to go through a url-shortening proxy to get to a page that is not blocked, but the url-shortening site is, you will be blocked from accessing a lot of content simply because you don't know its real url.
Ah, perhaps I misunderstood. I thought political censorship pressure meant the government pressuring the URL-shortening service to change the target of short URLs that people try to use to point to politically disagreeable content.
