Freedom of speech is one of the most important attributes of social network Twitter, which got a reputation for the decisive way a group of people or even countries can come together under a single goal.
The most recent example is the Egypt revolution that took place at the end of 2011, but also the other protests. In all cases, Twitter was a safe and effective communication channel for protesters, contributing to the way protests are organized and delivering correct information to the people.
As revenge, the Governments of the countries that suffered because of this decided to block Twitter at a national level.
Hoping to enter countries like Iran and Egypt again, but also other regions of the world where freedom of speech is taboo, Twitter is trying to soften the hostile attitude of political regimes by allowing local censorship of messages that contain specific keywords.
The communication blocked this way will be replaced by a warning message.
The good news is that Twitter will not delete the censored messages permanently. The messages are only blocked in the countries where censorship is in effect, but their contents will be available to other users.With a bit of determination it’s possible to overcome the censorship imposed by the regime, using a proxy server from another country.
