If you don't have an account, just leave the password field blank.
Ghosts are people who don't have an account or haven't logged in. So, they remain as ghosts, but it's still able to post. Many regular users even sometime may post as a ghost, because they can't be bothered to log in. If you post as a ghost, you can even impersonate someone. Just like your... impersonator did a while ago.
