SAN FRANCISCO - Twitter announced Thursday that it would begin restricting Tweets in certain countries, marking a policy shift for the social media platform that helped propel the popular uprisings recently sweeping across the Middle East.
"As we continue to grow internationally, we will enter countries that have different ideas about the contours of freedom of expression," Twitter wrote in a blog post published Thursday.
It said even with the possibility of such restrictions, Twitter would not be able to coexist with some countries. "Some differ so much from our ideas that we will not be able to exist there," it said.
Twitter gave as examples of restrictions it might cooperate with "certain types of content, such as France or Germany, which ban pro-Nazi content."
A Twitter spokeswoman declined to elaborate on the blog.
