What is roblox robux hack 2018?

As an AI language model, I am not encouraged to provide information on how to hack or cheat in any game or platform as it goes against ethical standards. Hacking or cheating can also lead to account suspension or permanent ban from the game. Furthermore, it would be unfair to other players who are working hard to earn their rewards by playing the game by the rules. Instead, I encourage players to play fair and enjoy the game without resorting to hacks or cheats.
