A friend wanted to know if he buys an account in Fortnite and can't log in with it, can he be banned from his other account?

A friend wanted to know if he buys an account in Fortnite and can't log in with it, can he be banned from his other account?

It is more likely to be banned on the purchased account. But probably on both

But if he signs up with it

Why do you buy an account that you don't use?

But could he be banned for it?

Again: why buy an account that will never be used? Since he can't be banned because he has never used it, that is, nobody can prove that the account has ever changed its users. But it is nonsense to buy an account that you never log into. You don't benefit from that

So doesn't he have to worry?

Why should he worry about something he doesn't really own?
