Someone reversing that out of this stupid article would be more interesting

I wish image editors would come with tools specifically for redaction. A solid colored box works but it's ugly or makes it hard to tell that there was anything written there at all.

What could be better is adding noise that matches the dominant 2 colors of the selection and focuses near areas of contrast. Then you can apply the pixellation on top of that and get something that's tougher to reverse.

Alternatively, it could try to recognize where the text and replace it with a string of random characters that are around the same size. In that case there would be absolutely no way to get back the original text since it's gone before the pixellation is even applied.

funny when people use burring to hide twitter usernames. its like you know you can just search twitter for the tweet verbatim and it will show the user, right?

That would be a lot more convincing if they had a blind demonstration. As noted in the readme, getting the CSS exactly right is both critical to making it work and extremely difficult. I'd wait until someone actually uses that software successfully in anger before we declare that you should never use pixelation.

Obviously black bars are better but sometimes you don't care that much about keeping the data secret.
