Indeed. And famously, using black boxes as a background on individual words in a non-monospaced font is also susceptible to a dictionary attack on an image of the widths of the black boxes.

Really, if you need to censor something create a duplicate without the originals. Preferably literally without the originals as the size of the black box is also an information leak.
- snotrockets 2y agoNo need for the monospaced requirement - it would reduce the search space, but it's solvable even before this reduction.
