Have you ever hand-written a word but want to hide it? One cross-out line doesn't do the trick. In fact, a full minute of trying to hide it with an ugly darkened-in box usually doesn't even do it. But if you just write a couple random letters over each existing one, people have basically no ability to recognize your original word. That is my one insight. Take it for what it's worth.
