This early on, I think best effort would be acceptable by the community, though you could go with strict copyright laws to be on the safe side as far as adding existential risk to the platform. Most sporting events are really, really clear about "no part of this broadcast or accounts of this event may be redistributed without written consent" blah blah, you get the idea. Should we respect that? Is it just a legal thing or is there something deeper there as far as building the world we all want to live in?

Exactly. But at the same time highlights are often left up by the UFC so it seems that a "sampling" tends to be allowed. I definitely do not want to do anything that could harm the platform though. It means a lot to me
