Twitter censors Pro-Life organization's tweet about a Christmas tree topper made of abortion clamps: Pro-life organization Pro-Life Action League tweeted the following: "Christmas is all about the joy and hope that come into the world with the birth of a child. There is nothing more anti-Christmas than abortion." It included a link to an article by liveaction.org about an abortion clinic that put up a Christmas tree and topped it with the clamps used to perform abortions. Twitter placed a sensitive content filter over the article preview in the tweet. Such filters do not allow users on the mobile app who have the sensitive filter enabled on their profile, the default setting, to view the filtered content at all. On the web version of Twitter, the users must click through the sensitive content interstitial in order to view the filtered content. Not only do such filters give the impression of inappropriate content, similar filters have been shown to reduce user interaction with content.
