How do I delete a FAF account?

I wanted to have a separate account for un ranked pass games vs regular ones but it seems that game history is linked to steam and not account.
So how can I delete the second account I made?

You can delete an account by contacting admin@faforever.com

Thank you!

game history is linked to steam and not account

Uh, I don’t think so. You can only link one steam account to one faf account. There should always be a 1-1 relationship.
