Since Twitch is imposing a limit on highlight storage and videos could disappear at any time, I'd like to suggest disallowing Twitch Highlights as an option for video proof in the future (as well as Twitch VODs, which have always self-destructed after 7/14/60 days).

Does anyone have arguments for or against disallowing video proof from Twitch Highlights/VODs?

Though it is true that any video could technically disappear from any platform at any time, I wouldn't want to take the risk of accepting a video with a higher-than-average risk of being deleted in the future, and Twitch's new limits create an incentive to delete old videos on their platform, making them higher-risk.

While this rule would effectively disallow most Twitch links, and it could be argued this increases the barrier to entry, I'd argue Twitch is also discouraging creating new videos in the first place with their new limits, and Twitch's "Export to Youtube" tool makes it relatively easy to move videos to a platform that (as of writing) has more longevity, and a better video player to boot.
