Can my mom ban me from Fortnite?

Am 20 years old

No you are of legal age and I think you are kidding me xd 😂

No, she can't. However, she is allowed to help you with certain household chores if you continue to live with her. And if you make noise with your rip-off at night, it can also prevent this, especially if you disturb others. And if she pays the Internet, she has power over routers and house rights anyway.

No! If you pay for it and help in the household… Otherwise: YES!

Right! Only kids play Fortnite… As far as I know?! O_O
