This question already has an answer here:
Today while I browsed around the SE sites I found an interesting answer on SciFi Meta SE. The answer can be found here if relevant. Since I don't have an account there yet I was prompted to sign up or sign in. So I clicked the link and was redirected to the confirm your new account page. Then I clicked on "Confirm and create this account" and was greeted with a 404 page, which is obviously a dead end.
How can I create an account on SciFi Meta SE anyway?
