Sure, Wikia-wide there is no policy. Wiki-by-wiki varies. On one of the wikis I Admin we don't encourage multiple accounts. I don't see any need (other than a bot account) for someone to have multiple usernames (unless you wish to hide part of your activity but that's sketchy to me). If you are blocked on one account, all accounts you are know as will be affected. One user had five accounts on the wiki and I banned all but one to help keep order.

In my opinion, two accounts max per user (as described above), but then again how would you go about enforcing such a rule? If IPs were used, multiple family members/friends could use the same computer or even worse if it was a public computer.
