What if I accidentally kill myself via gravity while running from a hunter, and the hunter reports it as intentional to the staff? I assume the staff would have to use their discretion in this case?

Yes in this case, it would be staff discretion, however in prop hunt, it's easy to tell. Usually (about 9/10 times) you see the hunters chasing or mentioning the prop nearby and then suddenly you see prop killed by gravity, and it reported.
It's MOST of the time easy to handle.
If the staff is unsure, it is best to let it slide in that particular case. Innocent until proven guilty, no evidence, etc, as that's how the servers work. You must have proof/be sure.
