Just one question, sorry if it's been answered before. Is there a way for you to view rejected speedruns of a game that you moderate? I just rejected a month old run because I am almost certain that the gameplay was slightly sped-up but if it's some obscure glitch or something, I would like to accept the run again. Would the second party just have to re-upload the run?

Go to the Runs awaiting verification queue and simply scroll all the way down to view the Rejected runs. To verify a run, open the run and click the icon with the three dots and click "Verify Run".

Ah right, I was clicking on the view all section and couldn't understand why I couldn't find the run, thanks for that!
