Feature idea: Score "proof" #960
Description
Some people like to upload footage of themselves completing a level, especially if it's about completing or acing a hard level, or just speedrunning a level or getting the highest possible score on it. A cool feature imo would be for people to be able to, using the API, add a URL to their score leading to a video, image or whatever else which proves they've legitimately beaten the level and showing how they've done it/achieved that particular score.
For the API we could also give users the ability to filter out all scores without proof URLs, which might potentially filter out some users' currently best scores if those don't have any URL but their older ones do. Admins (once mod role is implemented, also moderators, maybe also curators?) would also be able to add, edit or remove URLs if they're being abused (for example the video linked is for a completely different level, or shows a different final score).
