Yesterday I had a discussion with a mother in fortnite a friend filmed it. Can I upload it as a video on tik tok or youtube?
With your mother's permission, yes.
If all people who appear in the video agree, otherwise not.
Only if the mother agrees.
You'd need your mom's OK.
Still, do you really want to expose your mother?
If I were you, I would have a bad conscience for this aspect alone.
That was some strange woman I don't know
Oh, it said "one" and not "my" mother. Since you don't have that person's okay, you are not allowed to publish it, even recording that would be strictly illegal without the person's permission.
