CheckUser is a function of a wiki that investigates the IP addresses of an account to enforce blocks.[1][2] Together with manual inspection, it assists in uncovering illegitimate behavior such as spam.[3] This protects the wiki from disruption by any particular group or individual.[4] It can also show all edits from an IP including those by registered users.[5][6]
