Try to contact the game moderators by their listed social-media links. If no one respond, then use the support hub to request moderation for the leaderboard.

Try to contact them first via other contact possibilities outside of this site(youtube, twitter or whatever). If they still don't respond and/or verify your runs, then go ahead and request mod yourself from the support hub.

edit: I'm too slow

Longcats are very fast forum-predators. Don't blame yourself too hard.
