Any sites offering you free rewards, Builder's Club, or Robux are fake. Even if someone could hack the system, why would they want to help you or anyone else out? It's an attempt to get your password and steal your account!
Hey there. DO NOT listen to those who asks you to click links for ROBUX. All of these websites are fake and can expose your personal information. They would eventually hack your account if you trust them. DO NOT listen to them.
