The HG Role Playing Wiki:Multiple accounts

All the accounts a user controls will be treated as the same person. In short, registering another username does not allow someone to create a new identity for themself: it won't allow a user to circumvent a block or vote more than once.

Sock Puppets
An undisclosed alternate account used for disruptive or deceptive purposes is known as a sock puppet. If any of a user's accounts are to be blocked, then all accounts associated with that user will also be blocked. Please mark all known sock puppets with the template.

Alternate personas
There are legitimate reasons to use more than one account, however, like a user wanting to have a special username for a role playing "persona", or a number of reasons that may not be relevant on this wiki. A sock puppet must be openly disclosed as an alternate account belonging to a user's main account (please use the template). Remember: a user may still cast only one vote in any given poll. See Alt personas for a list.

It is suggested that an alternate persona's talk page be redirected to the main user account's talk page (so all communication with a unique user is in a single place).

Certain established users may also create a doppelganger account, which is to prevent impersonation by vandals. Please mark these accounts with the template. See Doppelganger accounts for a list of doppelgangers.
