I think I may have been in this game? I definitely had a teammate in a rappy suit named Katherine doing exactly as described.
I do want to also back up the response that it is not the person listed in the above post/screenshot saying we should ban this person, as the gamertag of the person I reported was not Jeeg the Ant.
When I reported the cheating player, their gamertag was TakedownPond69.
I don't have their Player ID off hand, but I can double check it when I get back on tomorrow.
