User accounts policy/zh-cn

Combining several proposals from this request for comment, this policy outlines Miraheze's views on account usage.

Shared user accounts
User accounts may be shared under the following conditions:
 * Shared accounts must be disclosed (indicated as being shared) on the respective accounts Meta userpage. This is to enforce the following condition:
 * Shared accounts may not be given any global permissions; it will be up to local wiki staff to determine if shared accounts should have local rights.
 * The reasoning for this is that, like not being able to track contributions of shared accounts reliably, any user of a shared account with global permissions could use those permissions, not just the real person that requested them.

Multiple accounts
Users are allowed to have multiple user accounts.
 * Multiple accounts belonging to the same person may be blocked as a group or individually depending on the severity of any misuse, this is up to the blocking/locking staff member
 * Users are not required to disclose multiple accounts, but failure to do so could be considered abuse of multiple accounts under certain circumstances. Please use common sense.
 * Keep in mind account creation can be considered a type of spam. Please only create accounts you intend to use.
