Fellas. The time has come to register for the most historic speedrunning event in the goi community. You only need a friend and a pc that can stream the game to participate. The tournament will be held on the 29th of May. The winners of the tournament will receive a hefty cash prize: previous tournaments having prize pools over $1000. https://discord.gg/CRcJSgDZ

All of the moderators are heavily involved in the community. You'd probably want to start there, not to mention uploading a video of your run.

If you take a look at his bilibili page (https://space.bilibili.com/255277565), he has around 30 runs that were sub 1:20 before he got his 1:10, he has obviously been playing for a while. Skepticism around a world record run is totally justified, however the mods wouldn't blindly accept a record run without doing their research. He has streamed before, showcasing he can play to that degree of skill, he's also made a video with a handcam. That said, it isn't irrefutable evidence that he isn't cheating - but proving innocence is a mountain of a task.
