YPPedia:Check user

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

Applications
Checkuser has four major applications:


 * Finding the range of IPs which are vandalising, so the said range can be blocked.
 * Finding what IP a vandalising 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.
