- We take a particularly dim view of people trying to hack or brute-force the site so please don't do it. There's no point in trying to poke about looking for answers to the puzzles on the PuzzleDonkey site because there are none to find. If we find out you have been hacking or brute-forcing we will ban you from the site.
