I got suspicious when investigating the connection between Leylapr2 and Mohammadghpr2 - based on their edits to Talk:Mohammad Ghorbanpour the connection was obvious, but I wanted to see if they had any more accounts so ran a CU. This led me to a clear connection with Chyah and a whole host of other socks. The ones I've listed here are all confirmed by CU investigation (same IP, same device), although there are a number of other accounts on these ranges which I haven't listed, as I cannot be certain they are connected.

This is a complex case, because it's cross-Wiki.

Sharp-eyed editor Koopinator identified Battle of Turkmen Sahra as a possible WP:HOAX, and put it up for WP:AFD; where it was deleted. Koopinator subsequently identified Rasa Salim Tehrani as another possible hoax, and raised the issue at Wikipedia:Administrators' noticeboard/Incidents#Editor created hoax article and did not explain or defend it. That article has been WP:PRODded (by another editor) as a possible hoax. Both those articles were created by Amirhosein Izadi.

Rasa Salim Tehrani links to Mohammad Qoli Salim Tehrani, another article created by Amirhosein Izadi. I have serious doubts about its veracity: the citations look impossible to find, and the English article contains more information than its Persian equivalent. That Persian equivalent, fa:محمدقلی سلیم تهرانی, was created by fa:کاربر:Rafic.Mufid. Unfortunately, I haven't worked out how to decipher dates in Persian WP edit histories to establish the timeline. Rafic.Mufik has been WP:INDEFfed on Persian WP as a WP:SOCK. The sockmaster is known on Persian WP as Sonia Sevilla; main investigation fa:ویکی‌پدیا:درخواست بازرسی کاربر/Sonia Sevilla; known socks in category fa:رده:سوءاستفاده‌کنندگان از حساب‌های کاربری زاپاس/Sonia Sevilla. The equivalent in English WP of that category is Category:Wikipedia sockpuppets of Chyah. This raises the question: is or is not Amirhosein Izadi a member of that sockfarm? (Around four, but not all, of the names in it are common to both languages.)

I know no Farsi at all, and am aware of Google Translate's deficiencies; but its translation of a line of classical Persian verse in the Persian article on MQST as "Oh by the sky's kiddie dolly wow we are all the time" strikes me as potentially problematic.

Counter-evidence, I have seen no sign in Amirhosein Izadi's activities of Chyah's obsession with Mohammad Ghorbanpour, so that WP:DUCK test fails.

Circumstantial evidence. (1) Amirhosein Izadi's User Page has a commendably professional look for an editor with just over a thousand edits. (2) Another contributor to the WP:ANI discussion raised the question of possible WP:COPYVIO issues in Amirhosein Izadi's edits.

I haven't notified the editor in question, because I don't know what the procedure is in these cases. Narky Blert ( talk) 22:18, 31 December 2019 (UTC) reply

• @ Narky Blert: I'm not seeing anything here that makes me think sock. As far as I can tell, Chyah and Amirhosein Izadi have no articles that both of them edited. The stuff about creating hoaxes may be true, but hoax does not imply sock. If you have some specific evidence of socking, please present it here, otherwise this will need to be closed with no action taken. -- RoySmith (talk) 02:18, 1 January 2020 (UTC) reply
