suppress distribution of a particular 32-digit hexadecimal number. but there are lots of ways to distribute such numbers online, especially when people are committed to keeping the number in circulation.
for example, one could take a photograph, and then using a hex editor, one could surreptitiously hide the number in the image data. or one could go completely balls-out and just replace all of the pixel data in the image with the number, in order to see what sorts of patterns emerge. one could even do this multiple times with multiple images.
