Because badspot needs to update the amazon cloud CDN for faster loading times and can't do that if he gets systematically banned as a joke.
it's more of a caching mechanism, if some trigger specifies that there's a new file that hasn't gone onto the cache for all players (probably working off of the master server), a script running on some server comes onto your server as badspot and retrieves the file and then uploads it to the cache, it repeats until all new files are uploaded, etc
