I think this kind of rule would be a bad idea and result in this rare niche community that is actually active to die.
I've always felt these kinds of requests and rules are weird because it's to make up for someone's lack of self control to not watch social media. If your schedule or timezone is as such you can't watch it live, it would be weird that you can waste time on social media before you have time to watch the race or a summary.
You really need to put in effort to get spoiled by results here. You're not getting notifications from here like with news app.
