Well, I see that no one has mentioned one of the most farcical
"cases" involving Jayjg.
The gist of it is that Jayjg and co (the now defrocked FeloniousMonk) were out to ban this editor (PalestineRemembered). Now PalestineRemembered (PR), being new, hasn't quite got the tricks to editing Wikipedia. He makes long polemical rants on talk pages instead of sticking to making biased edits to articles like Jayjg and co, and FeloniousMonk manages to conjure up some excuses to block him for a month (first block) and two months (second block). PR returns for his welcome-blocks and makes a mistake in citing sources where he reads a book which cites a primary source and inserts material into an article citing the book's source instead of citing the book itself (incidentally something which Alan Dershowitz did as well; see the "Dershowitz-Finkelstein affair"; and in which, curiously, Jayjg was involved in defending Dershowitz's side in the article)
Now Jayjg shows up and runs a google search on the source and it turns up in a holocaust denial web site. Jayjg, being the master of deduction and logic that he is, decides that PR's source is actually the holocaust denial web site and then, without questioning PR, bans him. When PR is questioning he admits his mistake in citing sources and produces the book where he got his material from. Somewhere between the block and someone talking to PR, an arbcom case is started, and the circus begins.
Now, its obvious that when the arbcom accepted the case they expected to be rubber stamping Jayjg; when it turned out that he might be wrong, most of them ran for the hills (similar to what happened with the Cla68 case). SlimVirgin and the usual gang suit up to defend Jayjg and turn the workshop into a meandering mess; there's a nice little conversation between SlimVirgin and 6SJ7 about how PR could still be a holocaust denier and how he could still be a visitor to the holocaust denial website, they just don't know; there's a nice little insinuation by SlimVirgin (who obviously hasn't read the book) that PR got his material from the holocaust denial web site because of some verbiage that appears in the website but not in the book (execept, ooops.... it's pointed out later by someone who has read the book that that verbiage does appear in the book). Basically the usual misdirection, false accusations, innuendo, and clouding the issue that these guys are so good at.
Most of the arbs have, of course, by this time, disappeared. There is a motion to dismiss (also strangely reminiscent of the Cla68 case), since obviously the case can only be about PR's wrongdoing and not Jayjg's. Jpgordan shows up to tell PR to basically suck it up and the whole thing disappears with basically no apology from Jayjg.
Interestingly, a couple of months later, PR is back on ANI (he still hasn't quite gotten the trick of editing wikipedia properly), and who shows up wanting to "mentor" PR....? Yes, User:Avi. The same user Avi who, it would later turn out, was in Jayjg's little gang of back watchers. His little trick seems to be showing up to discussions and pretending to be uninvolved and neutral, and yet always somehow ending up supporting Jayjg's position. The same Avi who is still apparently watching Jayjg's back in the latest case without quite disclosing that he was on the same mailing list the Jayjg used to coordinate editing articles with like-minded editors.
