For the fake JER, banning from chat is all we can do right now. The wiki software doesn't know how to ban a user with no edits, because as far as it's concerned the user doesn't exist.

As for creating sockpuppets for fun, we don't forbid people from having multiple accounts, only from abusing them. But if someone is creating large numbers of sockpuppets, for whatever reason, I for one would be inclined to call that abuse.

Impersonation is strictly forbidden, regardless of the purpose, and is grounds for a ban.
