Just curious as it seems to be a thing that may prevent those people who run away, do a move, run away again, rinse and repeat.
No, because then people would run away and taunt.
I don't think there is any taunt people can perform successfully and not be struck by a player chasing them. Think.
It's bad enough having 1 person stand on one side of the feld and Cake the stage or throw frisbees all **bleep** day long (I even encountered a Ratchet/Raiden team where the Ratchet Lv 3'd using nothing but his Down + Triangle. It wouldn't be so bad if it were a level where he couldn't run off and hide just to spam it again later - Invasion). Last thing we need is another excuse for people to camp and hide from battle
