Check User

CheckUser is an interface that permits authorized users to examine the IP address information of users on This fandom.The term CheckUser also refers to a user with such access.

Policy
The CheckUser tool is to be used to combat vandalism, to check for sockpuppet abuse, and to limit disruption of this wiki. It must be used only to prevent damage to any page or project.

The tool should not be used for political control; to apply pressure on editors; or as a threat against another editor in a dispute. There must be a valid reason to check a user. Alternative accounts are not forbidden, so long as they are not used in violation of the policy.

Stewards
Stewards may perform checks on users at this wiki if the outcome of the checks may result in global actions (global blocks or locks) being performed. This mainly includes cross-wiki abuse. Stewards must have tried to contact at least one local CheckUser or have a valid reason for performing this check themselves instead of local users. For the purposes of this section, IRC, on-wiki message, or any CheckUser-related mailing list (checkuser-l in particular) may be acceptable, but if questioned, a local CheckUser (preferably the one(s) the steward attempted to contact) should be able to verify that contact was made if it was done in any means other than an on-wiki message.

Stewards are required to notify local CheckUsers after they perform checks.

Usage
CheckUser may be used to verify a need for IP block exemption and to identify the target of the block if need be.

The tool may be used to investigate credible and legitimate cases of sock puppetry or abuse of multiple accounts in accordance with the alternate accounts policy. A credible and legitimate case of sock puppetry is one for which sufficient evidence, especially in the form of diff links, has been provided indicating likely abuse of multiple accounts.

The tool may be used to evaluate the collateral damage before blocking a range that has been used by long-term abusers.

The tool may be used to hardblock IP addresses or ranges of users when blocks of accounts combined with autoblocks will not suffice to prevent disruption. However, appropriate care must be taken when conducting these blocks to protect the privacy of registered users.
