Fugitives.
Fugitives are a special type of player in the game; they are wanted by the game, and the game does not issue Tickets to them through any channels. In other words, they have no way of obtaining Tickets, whether by clearing instances or purchasing from personal back-end.
Of course, the ways to obtain Tickets are not limited to those provided by the game. They could steal or privately purchase from other players, but the problem is, even if fugitives can enter instances, they won't receive any instance rewards after completion.
Although they can kill and loot money and Props within the instance, without instance rewards, it means that their Characteristics can no longer evolve, and there's also the risk of being hunted down.
