Galaga record holder was child rapist Stephen Krogman. Lonnie Cancienne--
who was arrested in 1999 for flashing an underage girl--had the record on Asteroids.
Four that I know of:
Stephen Krogman (Galaga and Arkanoid record holder, TG referee) - raped a 12 year old girl
Ron Corcoran (TG referee and director) - Child molestor
Lonnie Cancienne (Asteroids record holder, associate of Ron Corcoran) - Public masturbation, including in front of underage girl
Ron Bailey (Berzerk record holder, showed up in a TG documentary) - Raped elementary school boys
Billy Mitchell is an associate of the first two, and Corcoran in particular is pretty sick since his crimes were covered up by TG staff like Robert Mruczek.
It seems safe to say that if you ever wondered who was setting the high scores at the arcade, it was the creepy guy who'd hang out in the back all day.
