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.
In short, the accounts are duck blocked as per socks of LTA. Just wanting a CU confirmation as well as a sleeper check given the master is prolifically creating socks daily, let us put all the socks back into the wardrobe. --Cohaf (talk) 17:48, 3 November 2018 (UTC)
Zh.wiki admin Outlookxp said 'we without CU right, it is really difficult to deal with the meta-wiki.' and 'We don't have CU right now, and those foreigners don't cooperate, which makes me quite troubled.'--MCC214Talk with me#Contributions with me 11:33, 17 November 2018 (UTC)
Done the checkuser results are Inconclusive. Please base your blocking decisions on behavioural evidence. – Ajraddatz (talk) 19:29, 17 November 2018 (UTC)
Thanks Ajraddatz，all are duck blocked before this request, reported back, nothing else to do here.--Cohaf (talk) 23:52, 17 November 2018 (UTC)
Reason(s): User:Udha (master) is a prolific sock creator and edit-warrior in both the German (DEwiki) and the Albanian Wikipedia (SQwiki), who is inofficially backed and encouraged by one administrator there. He refuses to block his new sockpuppets even when there is evident proof that they're sockpuppets. Ever since he was blocked in July he used his own IP adresses to vandalize and editwar in the article of Ismail Kadare and has been creating one sockpuppet after another. These include: User:Tllja rikes, User:Glaukias etc. As soon as his latest Ips continue to war, we suspect that he created a new sockpuppet. Thise Ips seem experienced and in just a few days he has edited a lot of articles Udha and his socks edited as well. He insults and attacks people all the time. I have behavioral evidence as well, this means that the case is confirmed. As one of the people attacked by him, I confirm Tllja rikes is just another sockpuppet of Udha, created just 1 day after his latest socks were discovered and blocked. Please help us, as we don't know how to stop him.--Amarakuja (talk) 08:06, 4 November 2018 (UTC)
Not running check now, but No comment with respect to IP address(es) — regards, Revi 09:22, 4 November 2018 (UTC)
Due to the latest days activity, I can affirm that the blocked User:Udha in SQwiki is actively edit-warring in the article Ismail Kadare customizing it according to its own beliefs without discernment on the sober encyclopedic style it is needed, hence causing suffocating climate. Help much needed --Iskenderije (talk) 16:55, 4 November 2018 (UTC)
User:Iskenderije above is a sock as a checkuser here already confirmed. See above. I reported him as usual, so he might be a bit angry and wants to retaliate by making personal attacks. As for this particular request, it seems that user:Amarakuja has copy-pasted it from previous troll requests posted on this page by troll users. user:Amarakuja was blocked on SQwiki for being a sock see here and shouldn't be taken serious. Regards!--Udha (talk) 22:03, 4 November 2018 (UTC)
User:Udha just logged in with another sock User:Udha1 turning upside down the whole SQwiki with obvious biased charged without any common sense behind all this, turning SQwiki into a battleground where revenge and petty approach are the only criteria. --184.108.40.206 10:58, 5 November 2018 (UTC)
Reason(s): Appleeeeeeeeeeeeeee duck blocked socks. After a community discussion at zh:User_talk:Cohaf(currently moved to HAM page)，requesting m:CUP#1 to know the underlying IP of the accounts as well as to extend the autoblock or a range block by CU if needed. A sleeper check of course, although I don't think there will be any, for safety sake only.Cohaf (talk) 07:21, 5 November 2018 (UTC)
@Cohaf:I think you are referring to the talk page at your ZH Wikipedia account, so I fixed the link for you. - まっすろな未来 (talk) 09:08, 7 November 2018 (UTC)
@まっすろな未来:yes, thanks much. Currently the discussion is moved to the HAM page already. Stewards may take a look at the collapsed discussion there. Thanks.--Cohaf (talk) 09:14, 7 November 2018 (UTC)
Done - the accounts use a variety of widely-used IPs. The following accounts are Confirmed in addition to the ones listed: Vicky980128, RTTTTTTTTTTTTTR. The following account is Likely: Ken625. Please evaluate the behavioural evidence. – Ajraddatz (talk) 19:32, 17 November 2018 (UTC)
Reason(s): An old vandal who had the habit of vandalizing articles about television and radio. Titanic FM is the first account in chronological order , with no activity, and it was abandoned shortly. He come back with many accounts with similar names but has been blocked. Now he came back with this account and he vandalize another type of articles: about languages and countries. We want to be sure it is one and the same.--Kunok Kipcsak (talk) 13:03, 18 November 2018 (UTC)
