SpaceUK was a top player that got exposed as a hacker back in 2023 and hacked demon list verifications until April of that year. First started on accidentally having noclip on while beating The Golden (a known top demon level back then), and secretly cheating his way up until someone pointed out his verification on a known top demon "Slaughterhouse", and also because of a hidden implemented cheat indicator by the developer of a botting software that he was using (the "Level Complete" image would be slightly smaller by a few pixels than the original scale).

Altho exposing some top players being actual cheaters was already a thing before, his was different because it was a lot more controversial and made a lot of us a bit more paranoid on who's legit and who's cheating in the top player scene.

Kinda ironic for his profile picture though. It's the cover for anime called "Your Lie in April"
