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.
Reason(s): The above users are editing the same topic, all for the "OA2021" page, but the last user is using traditional Chinese characters. Therefore, we can't confirm their identity directly through It looks like a duck to me, so we need to check the relationship between these three users to help us confirm the relationship of these users.

Isn't this more likely to be meatpuppets in this case? For meatpuppets, checkuser doesn't help. In my opinion, it is possible to process locally rather than checkuser. Or can you explain another reason why this investigation should be conducted? --Sotiale (talk) 03:56, 19 September 2021 (UTC)
@Sotiale: The first user (代价竟是我自己) shows unusual familiarity about Chinese Wikipedia community, so I don't think it is a meatpuppet. They may be undisclosed accounts of established accounts (using undisclosed accounts in internal discussion is prohibited), or socks of recently WMF-banned users.--GZWDer (talk) 04:51, 19 September 2021 (UTC)
If so, I think blocking them is a good choice. If it is clear that they are sockpuppets or single purpose accounts, you can handle them locally. --Sotiale (talk) 05:16, 19 September 2021 (UTC)
In my opinion, it is meaningful to know 1. Who is operating them 2. How are them related and whether they are more accounts. If they are operated by WMF banned users they should be globally locked.--GZWDer (talk) 05:24, 19 September 2021 (UTC)
I'm still wondering why the first account(代价竟是我自己) isn't blocked. And if the first account is familiar with zhwiki community and its operation, are the rest of the accounts the same? I wonder if it's the same pattern as the first account. Thanks for your reply. --Sotiale (talk) 12:10, 21 September 2021 (UTC)
@Sotiale: There are not many edits to determine, but #2 and #4's comments seems not constructive (i.e. somewhat trolling).--GZWDer (talk) 15:17, 21 September 2021 (UTC)
I have main account in chinese wiki. The purpose I use this sockpuppet is to prove 城市君 isn't innocent and prevent revenge from WMC. I am not sockpuppet and meatpuppet of user name #1,3,4, and promise will not use this account to edit chinese wiki anymore. Pkease block my account. You can ckeck me if you don't trust me.
@Shanyuni: No matter who you are, it is prohibited to use undisclosed accounts to participate in internal discussion.--GZWDer (talk) 13:54, 22 September 2021 (UTC)
Reason(s): A CU is needed to check relationships between these users and that of w:zh:LTA:FROG. Thanks! --Luciferian • Talk 16:16, 24 September 2021 (UTC)
Note: All users have a similar user name with 不要亂 (lit. "do not indiscriminately"). Yet 不要亂風 denied their relationship with the others. Itcfangye (talk) 01:18, 25 September 2021 (UTC)
There seems to be a different opinion on HAM. --Sotiale (talk) 08:27, 25 September 2021 (UTC)
I've noticed it. I am considering withdrawing and separating the case. Itcfangye (talk) 14:59, 25 September 2021 (UTC)
Withdrawn. Further local discussion in progress with clear evidence 請不要亂刪^^ is a different LTA (through contributions). A separate request for 不要亂風 will be raised in local. Itcfangye (talk) 16:14, 25 September 2021 (UTC)
Reason(s): this two account has been consider as sockpuppet, but one(James_Dirant) mainly use zh-chs, and another use zh-cht, so check these two account from technical point of view is necessary.--Jonathan5566(talk) 13:03, 26 September 2021 (UTC)
Could you please check the status of your local request? I see this status word: 未转交. --Sotiale (talk) 13:23, 26 September 2021 (UTC)
I have fixed the link, there are two sections for the same users. An admin who blocked the user and closed the first discussion now agrees that CU should be performed.--Kuailong (talk) 14:27, 26 September 2021 (UTC)
