Can you still sell Fortnite skins?

Can you please elaborate on the current state of selling Fortnite skins? Are they still available for sale through official channels or have the policies changed? Are there any restrictions or limitations in place that could affect the sale of skins? Additionally, are there any alternative methods or platforms where Fortnite skins can be bought and sold? Understanding these details will help me better assess the current landscape and provide accurate information.
