Even randomized numbers wouldn't liberate you from the complainers. 69 and 420 would probably be the first to fall. 13, 88, and 14 would also likely get some people upset. And if you remove 13 but not 4, 17, 39, 616, or 666, you'll leave an opening for the complainers to accuse you of all sorts of biases.
