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): User Created many accout and use it for self promotion. Also he did some request for rollbacker, admin right. We think he is someone old user so please check also IP and find more account related this IP. Thanks.. आर्यावर्त (talk) 03:40, 5 June 2017 (UTC)
None of the accounts you list are blocked and Smoothest Aashu does not have edits. CheckUser is not for fishing. Could you please expand a bit why do you think those accounts are related? Thanks. —MarcoAurelio 08:17, 5 June 2017 (UTC)
Main 3 account Ashishsharma.in, TheINDIA and Ankitsharma3003 used wiki for self promotion. he created his own article named smoothest ashu on hindi wikipedia. also he doing as same on english wikipedia. we deleted this article but user TheINDIA created it agin. also this 3 account make comment for save this article. so this spam activity. also, user TheiNDIA new account but he act like old user. also he did some RFA: so we think this account is someone's shockpapet. we found smoothest ashu created 12 plus account on enwiki. this account is part of this many account. also use it for self promotion.--आर्यावर्त (talk) 09:49, 5 June 2017 (UTC)

Please don't copy the reasoning from the above request. We need to know the reasons of why a check is needed on azbwiki. —MarcoAurelio 10:15, 6 June 2017 (UTC)
Reason(s): LUMEA 2017 posted defamatory remarks about Romanian Wiktionary and me as an administrator on several Romanian language projects. Style, tone and content are similar to BAICAN XXX's (indefinitely blocked on all Romanian language projects, with a history of limited blocks on other sister projects such as en, de, it, fr, etc.). The user has a long list of known sock puppets, I just want to check if this too belongs to them so that I can make a decision as to how to proceed in this matter.

I support this request. I thought for a moment about indefinitely blocking the account on the grounds of "Duck". What's the probability of a single purpose account deploring on ro.wikipedia the absence from ro.wiktionary of an infamous incompetent user - especially when it comes to language? Plus Baican's well-known idiosyncrasy of referring to himself in the third person... --Mihai P. (talk) 19:21, 7 June 2017 (UTC)
Reason(s): Judging from contributions (at el.wikipedia and el.wikivoyage), he is the same user with the blocked user ΓΙΑΝΗΣ, with many sock puppets. He contributed three times with different accounts at the same discussion . Please inform me if there are other puppets too. C messier (talk) 11:09, 10 June 2017 (UTC)
User On ton has only one edit, but this was creating a sandbox with copy paste from the article about Thessaloniki Metro (one of the favorite subjects of ΓΙΑΝΗΣ, who regularly creates with his puppets sandboxes). --C messier (talk) 19:42, 10 June 2017 (UTC)
Reason(s): After Ovidiu Doman was blocked for repeatedly introducing false death dates in biographies of living people, last time at w:ro:Denisa Emilia Răducu, AndrewChief registered his account and introduced the same false statement in the same article last edited by Ovidiu Doman, this time with an edit summary.
