User:Mattisse has already been confirmed as a puppeteer, see Category:Wikipedia sockpuppets of Mattisse. In particular, many of these puppets went around tagging articles about pagan authors with multiple tags. In this case, the article Stephen Kent (musician) was tagged by Mattise [1] and then later by User:LiftWaffen [2]. But the most curious thing is that Liftwaffen is also editing an article which was created by another of Mattisse's socks, User:NothingMuch. The article is The End of American Jewry's Golden Era, and so far is has NothingMuch has created and edited it twice and now Liftwaffen is also editing the same article. See the article history.
Another interesting tidbit is this user's first edit is to create [3] a duplicate article Anne Hill under Ann Hill. The former article was created [4] by User:Flinders, another Mattisse sockpuppet. Following this, User:BlackHak adds a link to the article to Starwood Festival: [5].
I suspect that both User:LiftWaffen and User:BlackHak are socks of User:Mattisse. —Hanuman Das 01:12, 6 September 2006 (UTC)[reply]
For BlackHak, there is fairly strong evidence of sockpuppetry, namely that Ann Hill was created by new user User:LiftWaffen at 14:21, 2 September. The article is linked from no other article when it is created. Then User:BlackHak adds a link to the article from Starwood Festival at 16:23, 3 September. This looks like intentional misdirection. How did BlackHak find the article which is not linked from any other article. How did she know that it should be linked from Starwood Festival? Unless she is the same user who created Anne Hill, who was Flinders who was a sockpuppet of Mattisse. —Hanuman Das 13:11, 6 September 2006 (UTC)[reply]
User:BlackHak also asked a question,about the tagging on Village Pump (technical) [6]. Previously User:Capit (a confirmed sockpuppetet of Mattisse, although the user claims to be here grandchild) also posted a similar question on VP(T) of a similar nature[7]. User:Mattisse, has rescently asked questions there [8], as had another sock User:Massmato[9]. None of these questions are really on topic for VP(T), but it seems to be a favorite place to ask for help, so contribute a bit more evidence. --Salix alba (talk) 15:51, 6 September 2006 (UTC)[reply]
