 * Suspected sockpuppets

Editor is repeatedly using IP anons as sockpuppets to cast multiple "votes" in AFD discussions he initiates. Level of sockpuppeting increased after several of his nominations failed. Editor self-identifies on user page as associated with Los Angeles. Anons also associated by interest in vandalism involving UCLA related articles. These are lists of examples, there are more but this should be enough to show. There is an obvious problem.

 * I think I hear quacking as well ... that IP prod-2ing an article GMatsuda prodded is particularly damning. I'm gonna look more into this ... on the face of it, I'm not even sure if a CU is necessary. Blueboy96 23:03, 10 February 2009 (UTC)
 * After giving it more thought, I have blocked this user indefinitely. The fact that the great majority of the cited edits were in support of the main account's position was simply too compelling to ignore. Blueboy96 23:14, 10 February 2009 (UTC)

 * ✅ the sockpuppetry on AfD, though blocking will be hard, since he's on several dynamic ranges with substantial traffic. I blocked a couple of his static IPs, though. Dominic·t 08:51, 13 February 2009 (UTC)

Master account blocked, and socking confirmed by CU. All IPs that can be blocked without unacceptable collateral damage blocked. Mayalld (talk) 11:18, 13 February 2009 (UTC)

 * Evidence submitted by Djsasso

This editor has been editing the same intersection of articles. ie Los Angeles Kings and Manzanar which were areas focused heavily on by User:Gmatsuda and not a group of articles that is common to edit at the same time. Also the User:Kingsfan011 account was created 7 days after the Gmatsuda account was blocked for sockpuppeting. -DJSasso (talk) 13:09, 19 August 2009 (UTC)

From a technical standpoint, I'm not sure. is, but the CU log from February seems to indicate that he was editing from the same ranges as. J.delanoy gabs adds 14:57, 22 August 2009 (UTC)
