Wikipedia:Sockpuppet investigations/Yakudza19/Archive

Evidence submitted by DAJF
All three accounts were created between late October and early November, and have all concentrated primarily on editing (mostly edit warring) Takayuki Kubota and Takayuki Kubota (artist) as well as a few other related martial arts articles. Similarities in editing style include signing (with four tildes) edit summaries, and it is interesting to note that all three user IDs have been equally active in editing versions of the same two articles in other Eastern European language wikipedias, e.g. here, here, here, and here. User:Sensei 0208 appears to have stopped editing (as of 10 December) following a warning about possible sock puppetry, but the other two IDs remain active as of the time of this report. --DAJF (talk) 12:41, 14 December 2009 (UTC)

I added User:Dragon24 to the list after the initial report was submitted. This is another account created at the same time as the others, which has been involved solely in editing Takayuki Kubota. It had been inactive since 4 November, but suddenly resumed editing today, minutes after the other accounts received warnings about sockpuppetry and edit warring. Coincidence? --DAJF (talk) 12:59, 14 December 2009 (UTC)

Added User:Shihan 883 to the list. The account was created in late October and has been inactive since 2 December, but was involved almost exclusively in editing the same articles as the others listed above, using the same style of adding four tildes to the edit summary. --DAJF (talk) 13:11, 14 December 2009 (UTC)

Comments by accused parties
See Defending yourself against claims. All these persons are not sockpuptes. They are started from ruwiki. Adding four tildas is a common mistake, because in ruwiki it's placed just above edit summary. Thanks for noticing that - I will not do that again.

Those people are meatpuppets neither. All of them (as do I) are grown people (21+) and have their own mind, so they have right to vote and describe their point of view. Yes, we do collaborate on the martial arts theme, but each making its own part.

Dragon's (thats my girlfriend) editing today is a coincidence. But I never thought, thats editing a template is a bad thing. Many people made edits today on different articles that Im working on, including user:DAJF for example | here - coincidence?

Comments by other users
Please note that these accounts are under suspicion because of their participation in edit warring: see User_talk:Sensei_2105. New users are welcome but we do have an existing Manual of Style that should be respected. I would expect people from ruwiki would have better understanding of the need to discuss issues rather than edit warring. jmcw (talk) 20:35, 14 December 2009 (UTC)

Self-endorsing for CheckUser attention. I think technical evidence can help here. MuZemike 20:01, 15 December 2009 (UTC)


 * ✅ as the same user, not that it's much of a surprise:
 * It is  is the same user - their ISP is the same, but the useragents don't match up. The timing of edits on December 14th doesn't rule out the possibility, but the two computers involved would have to be fairly close: Sensei 2105 @ 12:43 Dragon24 @ 12:52
 * Yakudza19 is ❌. Hers fold  (t/a/c) 02:09, 16 December 2009 (UTC)

 * OK, thanks. I wasn't certain on a couple of the accounts, which was my basis behind endorsing CU. MuZemike 02:12, 16 December 2009 (UTC)

Conclusions
The Senseis and Shihan indefinitely blocked and tagged. The others remain unblocked as they are likely not socks. MuZemike 02:17, 16 December 2009 (UTC)
