How can I sell my Fortnite, so where?

If I want to sell my Fortnite account on Ebay, I get an email that I'm not allowed to sell it there, are there any other options?

There are some pages for account trading. For example, one would be this:

https://www.epicnpc.com/forums/fortnite-accounts.733/

Others don't come to mind spontaneously, it's been a while, but it's easy to find.

OK thanks

But I had once put my Roblox acc in. No one had found it for over a month
