They all have systems of blocking access to some websites. Denmark established a system that blocks access to a long list of web pages, which was secret. The citizens were not supposed to know how the government was censoring them, but the list was leaked and posted on WikiLeaks. At that point, Denmark added the WikiLeaks page to its censorship list. So, the whole rest of the world can find out how Danes are being censored, but Danes are not supposed to know.
