Sorry probably against the rules… But stick their accounts in a raid boss horde mode where they’re unable to play the game at all. Just straight up stuck in a room with each other and forced to endure the greatest of all time beat downs. And if they do manage to escape turn friendly fire on and mark them as HVTs through out the game. Allowing the entire Destiny community to hunt them. Oh… and the cheaters can’t hurt or harm or do damage to guardians. It’s just a one sided hunt. Just a fun and terrible idea 😂😂😂
