COOL, I'm not a professional at Roblox scripts as I have only made 2, but an unlimited Robux script is impossible as Robux is encrypted and Roblox sees all transactions, also frauding Roblox is arrestable and they will permanently terminate your account if done, what you are suggesting is ILLEGAL and should not be done under any circumstances also I will add that you shouldn't follow any tutorials about free Robux or Roblox hacks as even if there real most sites have added redirects and fake download buttons.  also i used to develop a roblox injector called  some crap i kinda forgot but the server got sold and it was shut down
