i don't feel someone is going to go through all that trouble to splice together videos and say this was my full run in PAL or NTSC for SPO there is so much work required for that and for someone to go through all that i'm pretty sure you'll be able to spot inconsistencies no matter how small

Yeah, so for just letting the credits roll, you add another layer of deterrence for potential splicing in the future. It's extremely easy to just keep recording after you win, so should be very simple to follow with the huge upside of helping to keep the leaderboards clean.

That being said, any runs that were submitted before this rule was added will stay, including the one submitted by dpad a few days ago, as it's not fair to remove/reject any runs that followed the already existing rules at the time of submission.
