Thanks to user @Kitaru it was determined the placeholder submission I had placed on the leaderboard from a Japanese YT video was actually performed with autofire. They also provided additional information about the workings of the game and how autofire can be determined from watching visual gameplay.

In Japan, a Max Score is an objective often sought after in this game, is generally a challenged undertaken without regard for time. As such, some records presented to me has shown that autofire is generally allowed for these sorts of runs. Additionally, there is a lack of video available for these runs currently.

For the time being, I've removed the run, and clarified the rules to stipulate that the use of autofire is not allowed.
