I saw The King of Kong documentary when it first came out and remember Billy Mitchell was so hateable. There is nothing humble about a man who answers his phone: "World-Record headquarters, how can I help you?": https://www.youtube.com/watch?v=Wef2qDT5j3I https://www.youtube.com/watch?v=Wef2qDT5j3I He was caught cheating back then too, if I remember correctly, by sending a video that messed with the score. I am surprised they accept sent-in submissions from anybody in an age where videos are so easily edited, let alone from a notorious cheater. People like Mitchell will go as far as they can to win regardless of whether or not they deserve it, and I'm interested in hearing what the thoughts are in the industry around dealing with cheaters. I've seen some gamers beat records while on Twitch, which I don't really know anything about first hand but it seems somewhat more legit than a sent-in video, as there are people watching both the player and the game he's playing in real time. Are there any Twitch features that can tell if a game is really being played live? Otherwise, are there any obvious moves that should/could be taken to ensure legitimacy in gaming world records?
