It would be kinda nice if you could make lobbies where people have to solve like 3 basic math/logic puzzles to join so tiny tots and super impatient people don't join and then subsequently leave when they aren't the imposter and ruin the round.
Hopefully that will be at least partially discouraged by the reporting feature they mentioned they are working on (according to the in-game announcement that was posted a few days ago, which links here)
nonetheless, if the issue persists that's not a bad idea...
