Fortnite Account SELL MMOGA?

I see a lot of people where fortnite to sell accounts I wanted to do this too but do not know how I do that I have verified myself as a seller but now how do I do that how do I upload this account?

I would rather not do that, because you can also be banned because of Acc sales.
