Are Wikians allowed to create doppelgänger accounts? See wikipedia:WP:DG for more info. I could use it in two ways:
- to create an account with a username similar to mine so another user can't use it first.
- to create an account with a similar to a vandal and/or sockpuppeteer's username, make the password gibberish and install no email, and then disable it so the original vandal and/or sockpuppeteer can't use the account first
