Make sure you have a good reason for the check. It will only be accepted to counter vandalism or disruption to Wikimedia wikis. Valid reasons include needing a block of the underlying IP or IP range, disruptive sockpuppetry, vote-stacking, and similar disruption where the technical evidence from running a check would prevent or reduce further disruption.
Be specific in your reasons. Ambiguous or insufficient reasons will cause delays. Explain the disruption and why you believe the accounts are related, ideally using diff links or other evidence.
Make sure there are no local checkusers or policies.
Reason(s): More nicks: "Wszyscy mamy IP 194 149 88 126", "Ja też mam IP 194 149 88 126", "Moje IP to 194 149 88 126". I'd like to request a CU against these users and the IP address 22.214.171.124. On the next day it was blocked, new accounts started to show up and follow the same edit pattern. Sometimes a block was closely followed by another account creation. Nicknames from "Początkujący użytkownik" onwards have been already confirmed by a steward, I'm putting them here so a full history of this case is kept. There was a suspicion that some of these users correspond to plwikt's LTA Wikinger, see this edit. The next step I'd like to consider is blocking that IP with the "Prevent account creation" option enabled. Regards, Peter Bowman (talk) 21:26, 25 April 2016 (UTC)
Hi, apologies for the slowness in actioning your request. I'll take a look at this later today if nobody else gets to it by then. Ajraddatz (talk) 14:38, 28 April 2016 (UTC)
Reason(s): I want to felt become a checkuser in here. I'm trusted, I'm can't shared a any info. You can check myuser before you give me a checkuser Murbaut (talk) 07:03, 1 May 2016 (UTC)
This is not the place for asking for permission. And I can't see that you meet the criteria, so even if the request was places at Steward requests/Permissions it would probably be closed as "Not done". -- Tegel(Talk) 09:04, 1 May 2016 (UTC)
Reason(s): This user has been heavily disrupting NL-Wikiquote over the last couple of days with a slew of new and old sock puppets. As we don't have local CU I can't block his static IP address for use by logged-in users. This user has a history of this kind of behavior on NL-Wikipedia (see:  (which is how I know he has a static IP adress) and . Concrete questions: are there any more sleepers? What are the IP addresses used (send through email). Whaledad (talk) 00:09, 2 May 2016 (UTC)
Hi, Sir Statler, For old times' sake, Devil's Revenge, Arjuna and Graaf Dracula are Confirmed. Long ago... is inactive so I was unable to verify; ReltatS riS IS Sir Statler (redir between userpages), Ilovechersonissos is not a valid username. The IP used is currenntly blocked on nlwikiquote. I found also one more connected account: Hutsefluts, not yet blocked. einsbortalk 15:45, 2 May 2016 (UTC)
Thank you for this Einbor. The last edit of my account Hutsefluts was 30-12 2010, so it was also inactive. We only had a big fight. Graaf Statler (talk) 21:07, 3 May 2016 (UTC)
Reason(s): Both user involved in vandalism and irrelevant page creation. I have given warining and guide, but user seems busy by removing them. Check is there any other accounts that related to them --AntanO 08:30, 2 May 2016 (UTC)
These are all Confirmed. No other users found. --Stryn (talk) 16:53, 3 May 2016 (UTC)
