Make the rules few and simple, but the punishments harsh.

Despite noble intentions, more rules eventually lead to less fun. I say do what you did for LN2, LOD and the like: if you can't monitor it then just make it legal. And lifetime ban anyone who cheats. Sure, they'll cheat again under a different name - but that's life. Ban em again. And again. Frankly, the people consistently at the top end up having a face to match the name eventually.

Videos seem like no big deal, but that's a big PITA. Might be easy for those of you doing group endeavors, but I bench alone in the middle of the night when the family is asleep. Tending 2, 3, 4 pots while refilling my thermos and adjusting ROG connect or EVBot, then refilling my thermos again, then assembling a screenie without coldbugging one of the components ain't always easy. I'm not excited about the idea of tending a camera too. Nor do I care for the idea of leaving it on for 6 hours, then spending my time going through the thing to find the bench in question. Especially since people who cheat won't have any qualms about making the video show (or not show) what they wish shown (or not shown).
