I wonder if a better (albeit slightly more involved) process to make blurred out sensitive inputs for shared content would be to: 1) add a block over the text, but use the same color as the form in put 2) add similar looking, but fake text on top of the block 3) apply the blur/pixelation. This way you keep the nicer aesthetics but you get the benefits of using the black box approach. Probably overkill for many cases, but when I create any sort of content I like to keep it looking fresh.
