Twitter places sensitive content filter over Christian message: Matt Barber, a conservative author, cultural analyst and syndicated columnist tweeted a photo of the back of a semi-truck that has a Christian message attached to it. The message reads "Blood donor saved my life... His name is Jesus Christ." Twitter placed a sensitive content filter over the quote forcing users to click through the interstitial to view the graphic. Not only do such filters give the impression of violent or obscene content, but similar filters have been shown to reduce user interaction with content.
