Why is there no "friend filter"?

I'm not complaining. I am just saying they should have filters for gamers who use foul language often, due to rage, that way people don't get offended. And even if playing with friends it is still Xbox Live which consists of other random players. And as
adults we know there are many adults who use foul language. I'm not saying the filter will be for everyone that's why my suggestion is an optional filter for those who use the language and enjoy talking to people who use it in a fun way where no one gets offended

Thank you. Thats unfortunate. They live in two different towns. I was hoping there was a way to lock in a certain friend list for him but there is not. Microsoft should look into that. It would give more kids access to more games. I know hes only 10 but
hes like every 10 year olf wanting to be like his 12 year old cousin.

They could play together but you would need 2 consoles to do so. Unless they took turns playing on the same console.

Fortnite has a PEGI rating of 12 that means it is not suitable for persons under 12 years of age. I would not allow a 9 year old play Fortnite for that reason alone.

And you can restrict a child account from the privacy settings preventing online communication yet you can't pick and choose a list of online friends.

Hi you can monitor things if you set up a family account. You can set time limits and content restrictions. Authorize purchases and downloads. A lot of parents use this feature. Here is the link to get started
