The players waiting in queue using their camera POV model to grief the players. There's a bit of that going on right now.
It's a cool feature and adds to the atmosphere of people "physically" watching your matches.

They either go into your camera, or go into your joints to grief your movement. I'd suggest to either make their model transparent enough to see through it, or to remove your own personal camera while you are participating in the fight.

Couldn't really capture it, but there's nothing stopping me from just going to blue's model, or their camera and being a wall.

If other features that original Toribash has that are going to be added in down the road, it would cause major disruption. Betting, dueling, tournaments. Even for the casual fun experience, it's bothersome.

maybe just lock the spectator model to outside the dojo, like spectator can still get close up inside the dojo but youll only see there model outside of the dojo
