Perhaps a "program" that adds meaningless errors, to disguise the author, would be useful?
"Program" in quotes, because obviously a web service is a bad idea, giving someone else the original and mark-up (assume they'd store it in a database).
So: I'd write a GPL script (Python probably) and release it for free, that someone could run on their own machine and it stores no data.
Would leave numbers alone, but transpose some letters.
Was proven decades ago that words that start and end with the same letters, but the middle is all jumbled, are still mostly-recognizable. And I recall a script was written for that; so, it or a derivative could be used for your idea.
This search has some interesting results, for further research:
