On TTT, if you go onto the f4 menu and into your inventory, you can click onto your skin which you are currently wearing which will unequip it and make it so that the skin you get is the dark grey character sometimes you see when people spawn in, It prevents people from IDing bodies and whenever someone dies without the skin it just stands up straight as if it is still alive without a name. It is getting used to advantage since when people die they do not get their bodies ID'd and the animations don't work which causes glithces for the hitboxes.
edit: I think it only works with a few skins, e.g: han solo or some anime skins
Some proof when I died the glitch to show the proof:
