Hi I am a moderator of paper io 2 leaderboard and recently all the leaderboard scores have vanished and some of the run sections have vanished too, the whole leaderboard just seems to have corupted or been lost.

It looks like a now banned user rejected a bunch of the runs on that board, if you check out runs awaiting verification and go to the rejected runs section you'll see ones rejected, the user probably changed other things as well and you'll have to look at the audit log for that

Might need to ping a mod to restore a backup
