Twitter places sensitive content filter over Christian message graphic: Matt Barber, a conservative author, cultural analyst and syndicated columnist tweeted a photo with the words "Faith is not believing that God can, it's knowing that He will." Twitter placed a sensitive content filter over the graphic, 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.
