I can't see any official policy on videos that are made available online for a short fixed period.

I'm halfway through a really good production of Twelfth Night by the National Theatre (https://www.youtube.com/watch?v=aig5ObghHS4) and was thinking of submitting it, but decided against it because it will be taken down next Thursday. Today I saw Ant put up Phantom Of The Opera that's got a two day lifespan.

Since I've seen more of these popping up since the lockdown, I thought I'd check if anyone had any opinions on etiquette for mayfly videos. Should we avoid them? Should we put the expiry date in the title? Should we kill them again a while later? Or should we treat them like any other video, since all life is fleeting?
