Personally, I'm extremely glad to see the new administration at Twin Galaxies is fulfilling its promise to clean up shop and get rid of the petty corruption that defined previous administrations. I think this will prove to be great for Twin Galaxies and classic arcade gaming as a whole, even if it causes turmoil on the short-term.
Note: Keep in mind that, while he has been proven to be a cheater, the depiction of the events in The King of Kong is inacurrate and ought not to be treated as gospel.
Based on the complete body of evidence presented in this official dispute thread, Twin Galaxies administrative staff has unanimously decided to remove all of Billy Mitchell's' scores as well as ban him from participating in our competitive leaderboards.
We have notified Guinness World Records of our decision.
