I support this enough to make a comment in addition to upvoting. Whenever I check the wiki's recent changes page, way too many of the recent changes are spambots creating accounts or Vladimir_Nesov killing them. As MixedNuts points out, the code end is difficult, but the fix would be highly appreciated.
I'd like to see, beside the cumulative karma as it is now, also its analytic. Does my 0 points somewhere means no upvotes and no downvotes or +7 and -7, for example?
A timeline graph would also be appreciated.
