'''​THAT GAME AND MAINTENANCE GUI IS A SCAM FOR PEOPLE TO GET INTO YOUR ACCOUNT! '''​By inputting your login information into the GUI, someone will have access to your login information and can then log onto your account (and can lock you out of your account, sell all your limiteds, get your account banned, etc.).

The best thing you can do is immediately leave the game and report it to ROBLOX through the Report Abuse system.
