Regarding the rejected runs issue - rejected runs actually get into the list immediately. However, just like the "runs awaiting verification" list is limited to 50 runs; the rejected runs list is also limited to 50 runs, with priority to show older runs. So, you only see new rejections after the old rejections go away from the list (after one month).

The "show old" button for rejected runs is also useless, because it is also limited to 50 runs, and show only the 50 most old rejections in your games. (In my case, most of them are not even my rejections).

ok i tested it and rejected runs are listed on users pending actions. so you should ask them to provide the link to the rejected run.

honestly the problem also is that the site honestly isnt made for extremly big games or for moderating a ton of games.
