CheckUser is a tool which is used by users in the checkuser group to effectively fight vandalism.

Applications

Checkuser has three major applications:

• Finding the range of IPs which are vandalizing, so the said range can be blocked.
• Finding what IP a vandalizing account uses, for the purpose of effectively blocking it.
• Finding which users use a common IP, for looking into abuse of multiple accounts.

Under no circumstances is the CheckUser tool to be used in any other fashion, and especially not by a curious checkuser who wants to know a user's IP.

CheckUser log

The CheckUser Log is available to other CheckUsers here. However, as only CheckUsers can see the log, CheckUsers are encouraged to log their actions here for all users to see, but removing the data that can be used to link users and their IPs (as a CheckUser use typically involves getting an account's IP(s), then checking the accounts associated with the IP(s), thus a raw log is easy to deduce what IP corresponds to what user). An example log entry is below:

• 22:53, 30 January 2011, Example got IP addresses for Insert vandal (Talk | contribs), and followed up by getting user(s) for the IP(s) returned (reason)

Which uses the code:

{{checkuser log|type=ip|date=22:53, 30 January 2011|checker=Example|user=Insert vandal|reason=reason|follow=y}}

Requesting a CheckUser

If you need a checkuser and the situation conforms to the above rules, you can either contact one of the checkusers directly (via their talk page or any other method), or post a request on Administrative requests.
