Wikia (the company) doesn't have any specific policy or statement against sockpuppeting or the usage of multiple accounts, and it's not forbidden by any means. However, many individual wikis do have their own guidelines against sockpuppeting and may choose to block someone who is sockpuppeting in order to enforce their own local policy. As a general rule of thumb, I think sockpuppeting is generally frowned upon or has negative connotations. But that's slightly different from saying that sockpuppeting is "forbidden" on all wikis -- it varies from wiki to wiki. That's basically what Ricky Spanish was saying above.
