All edited Chang Yi Wang with promotional content. Recent page history tells the story. User talk:Cmhu has more info. It's possible Cmhu is unrelated, but the other three are all the same based on same article, same content, same times. Green C 07:07, 7 September 2022 (UTC) reply

Added 5 more including the oldest and creator of the article User:Chihjunglin. All accounts except Cmhu are SPAs for Chang Yi Wang. They follow similar patterns of being undisguised throw-away accounts, edit in a promotional manner, use honorifics "Dr. Wang". -- Green C 18:51, 7 September 2022 (UTC) reply

Looks like Category:Wikipedia sockpuppets of Ubiait was recently created by User:Materialscientist, not sure if they knew about this SPI. -- Green C 19:21, 11 September 2022 (UTC) reply

Accused parties may also comment/discuss in this section below. See Defending yourself against claims.

This case is being reviewed by MarioGom as part of the clerk training process. Please allow him to process the entire case without interference, and pose any questions or concerns either on his talk page or on this page if more appropriate.

• CheckUser requested and endorsed by clerk - based on behavior and timing, it's clear that Ubiait, Seoksoon, Ironsj A, and Csdaag are socks. The rest are probably MEAT, and based on Commons contribs, most likely UPE. The non-stale group is blocked now, and I assume Materialscientist have run some checks already, but endorsing for a last look at the whole case. Please, check if any of the apparently stale accounts turn out to not be stale. Thank you. MarioGom ( talk) 06:00, 12 September 2022 (UTC) reply
