If I am standing over the opponent, and purposely fall on top of them into mount or into their guard…if while I’m falling & my knee lands on his face

Would that be an illegal knee or would it just be seen as a grappling accident? It’s not like there’s any wind up and my leg wouldn’t be coming off the floor. So if I go from standing to kneeling like a knee on belly but on their face is that a knee strike or a way to pin the opponents head in place? I see the opportunity for this attack all the time and it seems like no one has thought about it, tried it, or it’s against the rules.
This would be very easy to make look accidental.

To illustrate more, if I am being armbarred in my opponents guard, and I stand up to try and slip out which forces him to let go so I purposely fall down to try and keep my weight on the opponent and top position, while I’m doing so my knee lands straight on his nose.

Walker got away with a back flip knee to the face and people let it go immediately.

The rules are hilarious.

It would either end in a No Contest due to illegal strikeor if the ref thought on purpose a Disqualification

This. No contest if an accidental illegal strike alters the complexion of the fight.

If I accidentally fed my hand through your long hair but didn't grab it. Could I use it to pin your head down to the canvas

Wasn’t the Michel Perreira on Igor Poteria? If not, it’s happened twice
