My sense is that Wikiabuse was created (a) out of a sense that Wikipedia cannot be trusted to provide an accurate history of what's going on in it, and (b) that there's a need to be able to look this stuff up about admins without having to sift through dozens and dozens of diffs and comments and such. I make no claim as to being inclined for or against either of these-- well, the second, if well executed, would make it easier to understand the disputes. But I see from what little I've followed this on WR that the creators of the site are pretty disappointed in it. And I also think it's about time that admins accepted that they are going to be subjected to public, off-WP criticism, and get a thicker skin about "attacks".
