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.
