Don't be fooled by websites wanting to give you Free Robux in return for completing surveys as this is just a scam and waste of time, surveys are just a ruse to get information out of you. All that happens is you will be asked to complete a one-minute survey to prove you are not a bot and then you will be directed to another survey to prove you are over 18 along with the promise of receiving a certain amount of free Robux. What will actually happen though is you will be directed to a series of surveys to complete until you are eventually required to download something which will give your device a virus instead of Robux.
