After continued concerns about the dismal quality of certain unreferenced articles about living people, Messedrocker has compiled, through an analysis of article categories, a list of over 16,000 articles on living persons that do not completely cite their sources. The list is divided into 17 sub-pages; users are encouraged to review uncited statements, attempt to find sources or remove uncited, controversial statements, and correctly tag articles.

The WikiProject Vandalism studies recently finished its first study and has published its conclusions (a full and detailed copy can be found here).

The first study analyzed a randomly sampled pool of 100 random articles. Within these 100 articles there were a total of 668 edits during the months of November 2004, 2005, and 2006. Of those 668 edits, 31 (or 4.64%) were a vandalism of some type. The study's salient findings suggest that in a given month approximately 5% of edits are vandalism and 97% of that vandalism is done by anonymous editors. Obvious vandalism is the vast majority of vandalism used. From the data gathered within this study it is also found that roughly 25% of vandalism reverting is done by anonymous editors and roughly 75% is done by wikipedians with user accounts. The mean average time vandalism reverting is 758.35 minutes (12.63 hours), a figure that may be skewed by outliers. The median time vandalism reverting is 14 minutes.

The planned second study is in a developmental stage; details relating to the study, which will involve a larger sample size, are being planned.

Meanwhile, one of the few user surveys of Wikipedians, conducted in 2005 and originally available only in German, was translated into English recently.

Certified.Gangsta presented evidence, in which he alleges that Ideogram has engaged in canvassing, wikistalking, and orchestrating an anti-Certified.Gangsta campaign. He also denies Durova's allegiations. Kirill Lokshin has proposed remedies placing both parties on revert parole, and admonishing Ideogram.

• Betacommand: A case involving the actions of Betacommand. Some of Betacommand's blocks have been questioned, and his bot-related actions have led to his removal from the bot approvals group. Betacommand has noted that he makes numerous username-related blocks, and that most of his blocks were appropriate. Whether Betacommand used his administrative account for bot-related activity, whether he is unique in doing so, and whether such an action should be allowed or not, have also been questioned. Paul August has proposed a remedy, with the support of four arbitrators, desysopping Betacommand; voting on other remedies is split.

A remedy placing Falun Gong on article probation has the support of five arbitrators; a series of other remedies placing various users on revert parole and/or banning them from Falun Gong and related articles and talk pages have been proposed, but voting on them is split.
