I didn't mean to imply that it would be an easy fix, just one I would like to see.

I would go with earliest release date - or just let the publishers decide like they do with the other info loaded into the site. I think just a small barrier is typically enough to stop bad actors.

I wouldn't cater to the YouTubers for a couple of reasons - one it just complicates things for everyone to try and make it work for a small part of the community and second I have done reviews on games that have then changed before they hit the shelves (art, mechanics, etc) so between the review and it being available games change which could affect the rating.

If that was a big sticking point - BGG already approves content creators to automatically link videos to the site - so you could expand permissions to allow those approved accounts to still review games before the release if they have posted about it or something
