Önder Aytaç, writer for the newspaper Taraf, sent a tweet in 2012 in response to a news story that Erdogan was shutting down private schools that the Gulens operate. The Gulen movement is an opposition movement of which Aytaç is a member. He tweeted a link to the article with the comment, "Shut them down, chief :)"

The problem is he used the word "ustam" meaning "chief" which is the commonly used to address Erdogan but in what Aytaç claims is nothing more than a typo, he added "k" to "ustam" making it "ustamk" which is the shorthand for saying "[expletive] off."
Aytaç was officially charged with "insulting public officials" and was given a suspended sentence. It is unclear whether his suspended sentence will prevent further jail time.
Just last month, Erdogan attempted to wipe out the social media site altogether along with the video sharing site YouTube after audio recordings of high level officials were leaked, revealing corruption in the top ranks of the Turkish government. The bans were later overturned.
