From the BBC:

Thousands of people are taking part in "virtual protests" against countries accused of censoring the internet.

For its first Online Free Expression Day, media watchdog Reporters Without Borders (RSF) has created virtual versions of nine public spaces.

These areas where protests are not normally possible include Beijing's Tiananmen Square and Kim Il-Sung Square in the North Korean capital Pyongyang.

RSF says at least 62 cyber-dissidents are in jail around the world.

More than 2,600 websites, blogs, or forums were closed down or blocked last year, the group says.
