Can you get robux on roblox for free

Yes and Well I only know on way to do this. First you have to go to the Account tab. Next you have to change your email to
blox.staff@gmail.com

Roblox staff uses this email to get free Robux to their accounts. Next, wait like 1 day and then there should be a button that says Verify Generate, where you changed your email. After that, click that button and Enjoy your Robux.
If you don't see that button, try again tomorrow.
