Wikipedia:Sockpuppet investigations/MasaoOhba1949/Archive

Suspected sockpuppets
Sock master claiming to be Soh Ohba has been making numerous unsourced edits to his own page. Diffs:
 * Sock master MasaoOhba1949 and socks 1 and 2 all share the name (at least in part) of the main target of abuse.
 * Socks 1 and 2 both bear the birth date of Soh Ohba.
 * IPs, mainly from range have done most of the unsourced edits.

Note: The first two entries are fresh with recent activity. I've also included older IPs that fit the behavior but are not already mentioned in previous investigation; not sure how useful it'd be beyond documentation purposes, considering they're likely stale by now. (2001:268:9800:0:0:0:0:0/40 looks pretty disruptive in general, beyond the behavior that unambiguously matches this sockmaster.)

Behavior Inserting mentions of "Ohba Soh"/"Soh Ohba", sometimes along with subtle or unsubtle vandalism. Also touches Masao Ohba and its mentions. Insofar as I am able to understand with my middling Japanese proficiency, fits behavior described by LTA case on Japanese wikipedia, mentioned in edit summary by an administrator : "Ohba Soh" and variants deleted and salted. Particular obsession with topics related to boxing, baseball, Japanese politics and politicians. Obsessed with Matsuzaka Generation, unduly adding people simply because they belong to that age group regardless of actual relevance (per the article on ja, the scope is limited to Japanese pro baseball players born between April 2, 1980 and April 1, 1981, and other celebrities who played in high school or college baseball with that cohort). It appears they are migrating / expanding their activities over to here, is a LTA case warranted?

Other: may also be related to baseball-related Japanese language spam in edit summaries that I came across a few days ago, but I'll have to see if I can find that again.

 * is ✅. No comments on IPs. The involved IP range is too wide and busy for a rangeblock, and the useragent is too common, so there might be sleepers and new socks. Materialscientist (talk) 21:51, 21 August 2023 (UTC)
 * Yogiyama2023 was tagged as proven to Marineslottechiba1992, which is tagged as confirmed to MasaoOhba1949. So I'm re-tagging Yogiyama2023 as proven to MasaoOhba1949. Closing. MarioGom (talk) 22:19, 27 August 2023 (UTC)
 * MasaoOhba has not edited since 2021. There's no point in blocking it. Feel free to report it again if it becomes active. MarioGom (talk) 16:44, 30 August 2023 (UTC)

SPA, recreated Soh Ohba, then logged out and removed the G4 tag repeatedly, and linked the article to several articles with all sorts of unsourced claims about him and his family: Democratic Party for the People, List of people from Hokkaido, List of members of Nippon Kaigi, Matsuzaka Generation, Chartchai Chionoi, Masao Ohba, Toshiro Mayuzumi, Japan Renewal Party, Otaru. Wikishovel (talk) 16:30, 3 December 2023 (UTC)

, Soh Ohba is deleted now, and the sandbox edits don't match what was deleted, so all I can provide now is diffs of the IP socks linking Soh Ohba to the other articles listed above. Would that be of use? Wikishovel (talk) 19:08, 4 December 2023 (UTC)

New SPA, first edit was a two-edit recreation of Soh Ohba at User:Miketyson1966, then pasting the result to Soh Ohba (Boxer). Wikishovel (talk) 13:54, 10 December 2023 (UTC)

Adding IP sock 106.146.122.178, which linked Soh Ohba from the same articles last week as is linking today. Wikishovel (talk) 14:47, 10 December 2023 (UTC)
