  • Inactive checkusers should be warned in their talk pages and by email (if they have set a valid email address in their preferences) before rights removal.
  • Inactive checkusers who had their rights removed can request to be reinstated as checkusers in the 3 months following their rights removal. After that period, they can only regain their rights by a new vote.

  • CheckUsers are elected by the community; they are admins (only technically if not elected as an admin before), but do not have any other "higher" local rights such as arbitrator, bureaucrat, or oversight (segregation of duties).
  • Local policy is at Wikipedia:Checkuser.
  • CheckUsers only act on request, which should be made publicly at Wikipedia:Checkuser/Anfragen, fact-based comments by other users are possible.
  • Private requests are allowed as an exception (when private data, e.g. real names are affected).
  • Public log exists, requests and decisions are stored on archive pages.
  • Strictly all checks (also those from stewards and Office Actions) are publicly announced (anonymised if needed, e.g. regarding user names).
  • Checkusers don't perform any bans/blocks, they leave the decision on this to the administrators.

Cases of the check
  1. based on 5 editors' public vote (but there must be more supporting than protesting votes), with valid reason and evidence/suspicion supplied
  2. based on 2 admins' private or public vote
  3. based on 2 editors' common request to prove that they are not each other's sockpuppet

CheckUsers are not allowed to run a check without one of these conditions.

  • CU access is appointed/removed by voting according to the global policy (at least 70%-80% votes of support and with at least 25-30 editors' approval). They are allowed to be administrators, but cannot be bureaucrats at the same time.
  • CU requests should be send by e-mail to the User:Checkuser which is checked regularly by local checkusers. It is forbidden to accuse publicly anyone for sockpuppeting.
  • After the check has been performed, and if a sockpuppeting is discovered, a checkuser report is given at local Village Pump. If the checking doesn't give any results, no report is publicly presented.
  • No public log.
  • Checkusers don't perform any bans/blocks, but recommend them, and leave the decision on this to the administrators.

  • As they are admins, checkusers can peform blocks, if necessary.

zh – Chinese Wikipedia[edit]

  • There are no users with CheckUser permissions since 30 March 2018 due to security concerns from WMF staffs.
    • In 13 January 2022, WMF announced the requirements to un-freeze CU elections, it's still unclear whether zhwiki community has acknowledged them or not.
  • Local policy is at zh:Wikipedia:用戶查核方針, note that some local users reported that some Stewards may not recognize it, and enforce just the global Checkuser policy for their zhwiki actions.
  • CheckUsers can act in one of these situations:
    • (RFCU) On request (public or private);
    • (CUP1) To block underlying IPs of an account, where the autoblock has expired or been ineffective. Sockpuppets found may also be blocked.
    • (CUP2) Collateral damage checks for the hardblocking of IPs or ranges.
    • (CUP3) IP block exemption checks before granting IPBE (or to verify it is being used constructively).
  • Currently, CU requests are handling at zh:WP:SPI with reviews, if there are reasons to believe that actions from Meta-Wiki are really needed, one of the administrators or SPI clearks may transfer the requests to SRCU.
  • CheckUsers may perform any blocks themselves; but it is not mandatory.
  • The status of CheckUser usage were available at zh:Wikipedia:用戶查核/統計.
