However unlike verified speedrun,there is no ranking as its denieded

i dont see a reason for rejected runs to show up on leaderboards but i think they could have a section on the user profile

There's a reason why that feature already exists but is for moderators only...

can't wait for Minecraft to have the rejected leaderboard, tied 1st place with 1000 1ms rick rolls that insult the moderation staff in the description.
but sorry yes @SioN is quite right, no reason at all for them to appear on the leaderboard and mods do have the ability to look through rejected runs, people may not want the reason publicised and it would be incomplete with many people deleting their rejected runs.
