Turkey is one of the world's most active countries on social media. So what happens when Twitter is blocked there? Millions of tweets from Turkey, that's what.
Turkey's Prime Minister said late on Thursday that he wanted to "wipe out" Twitter using new laws, and soon after users in Turkey reported that they couldn't access the site. This led to a deluge of tweets being posted via proxy servers and SMS throughout the night.
