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): It appears that the accounts were mainly created to vote against deletion of the paper nominated in this AfD: w:fa:ویکیپدیا:نظرخواهی برای حذف/مینا آقازاده . It would be useful to know if they are actually socks, and if there are more such socks for that main account. Huji (talk) 04:03, 25 June 2015 (UTC)
Checked! Farzan_f and Nastoran_z looks for me Possible, but I can see no connections beetween them and Panorama2. einsbortalk 06:41, 25 June 2015 (UTC)
Reason(s): They have multiple patterns of usernames: either nonsense characters (for most of them) or Arunrajan* (for two of them). Requesting a check to root out possible sleepers. Based on the username pattern I am also suspicious of Agsfdgh (talk • contribs • block • SULinfo • x-wiki • recent edits • CA), as it was created in close proximity to the other spambots, but I'm less sure with that one.--Jasper Deng (talk) 08:49, 29 June 2015 (UTC)
All are Confirmed, found some more. Locked all and globally blocked the underlying ip--Shanmugamp7(talk) 09:14, 29 June 2015 (UTC)
Reason(s): User sq:Përdoruesi: Tifoz i Futbollit is a new user that appeared today (all his edits) in the Albanian Wikipedia and immediately made edits in his talk page (link) - that shows he is a experienced user; he also voted in a poll for the nomination of a good (perfect) article (link). Albanian04, another user that had voted in the same poll is currently blocked for using a sock. --Mr.PseudoDon't talk to me 12:27, 29 June 2015 (UTC)
Tifoz i Futbollit and Sadsadas have same IPs and soft. No connections beetween them and Albanian04. einsbortalk 11:05, 30 June 2015 (UTC)
So, Tifoz i Futbollit = Sadsadas; or is there any other interpretation? --Mr.PseudoDon't talk to me 11:38, 30 June 2015 (UTC)
They can be two different people using one computer, according to CU data they can belong to one person. einsbortalk 11:46, 30 June 2015 (UTC)
Reason(s): It appears that the first user creates the two others users for persistent vandalism of the page ET1. But they thing that me and the other user with the name Jeanis 12345, we are pupet accounts and control us the user Γιουγκοσλαβια. Please, do the checkuser so prove that we don't have any relationship. Timmy terner (talk) 13:36, 1 July 2015 (UTC)
