TWITTER has refined its technology so it can censor messages on a country-by-country basis
Probably its a good way to "conquer" other countrys like iran and china."Some differ so much from our ideas that we will not be able to exist there. Others are similar but, for historical or cultural reasons, restrict certain types of content, such as France or Germany, which ban pro-Nazi content," Twitter said.
But now can also censor other 'uncomfortable' contnet like citizens questions about sopa/pipa/acta projects
