Kato noted in another thread recently that the incident in which Durova wrongly blocked !! is now being mentioned in literature on Wikipedia's history and development, I'm sure much to Durova's chagrin and bemusement. Giano's block today shows that the incident's legacy is still raw with some editors.
The major significance of the incident is, I think, that it was the primary death blow to SlimVirgin's and others attempts to use cabalism to control Wikipedia and promote their own agendas. Giano is to be thanked for refusing to allow Jimbo and other Wikipedia admins to cover it up. This incident, along with SV's decision to deny Wordbomb due process when he tried to complain about Gary Weiss' use of Wikipedia to promote his personal agenda, I think are the two main events which (eventually) brought down SV's powerful and influential clique.
If you all notice, I don't criticize Durova much in this forum like I do SV, JzG, Jossi, Jayjg, or other members of that clique, because I personally don't think that Durova was as malicious as those others. Those others were, in my opinion, waging a dishonest and unethical campaign to use Wikipedia for their own advocacy and propaganda on topics that were important to them. I don't think Durova was trying to do this. I think in Durova's case, she had fallen in with that group and sincerely (and mistakenly) believed that they were the "good guys", no doubt reinforced by the fact that Jimbo and at least two arbitrators were on at least one of the mailing lists which that group operated.
Others have stated that one of the primary activities of that mailing list was to complain about banned editors coming to Wikipedia Review to continue their nefarious activities against Wikipedia. Durova apparently thought she was doing the right thing by trying to fight against this campaign to destroy Wikipedia. She must have been dismayed to find when it hit the fan after her block of !! that neither Jimbo nor any of the arbitrators on that mailing list really came to her defense.
Durova could have done a better job making amends. She should have given !! a better apology than she did. She also should have renounced that mailing list and the leaders of it. I've been told that the members of that list had to promise not to talk about it when they joined. Durova didn't need to repeat any specific conversations, but she should have revealed who was on the list that she emailed her Sekret evidence to and why she felt that they would be receptive to what she was doing. If she had done all of that, I think she might would have been able to put the incident behind her better. More importantly, that would have been the right thing to do.
Durova does fantastic work finding and uploading images. Her evidence against Jossi is one of the main reasons why that POV-pusher is now, thankfully, banned. Otherwise, Durova seems to make poor decisions about the wiki-political positions she takes and personalizes them too much. Perhaps she is angry at the ArbCom members because they wouldn't come to her defense after the !! block even though at least two of them were complicit in it (at least one of whom is no longer an arbitrator). Well, she needs to look at the bigger picture and realize that it really isn't about her, it's about the conditions and environment in Wikipedia which allowed that incident to happen and why Wikipedia needs a better governance model to ensure that it never happens again.
Sorry for the verbosity.
