How would the blame maps work with people editing
around vandalism? For
example someone either blanks the page or does extensive vandalism to it
(especially over the course of a couple days or a couple users). I would
imagine it would be fairly easy if the bad contributions just got rolledback
but would the old blamemaps still be reinstated if someone went in and
manually copy/pasted the old version (or something very close) in or would
the system count it as a new contribution?
I haven't been following this in any particular detail - I have no
intent of using the system! - but this is certainly an issue they have
thought of and planned for; they currently describe the system as
"robust to cut-and-pase, delete-and-reinsert, and most type of
attacks..."
I suspect the papers linked at the bottom here -
http://wikitrust.soe.ucsc.edu/index.php/Main_Page - go into a bit more
detail about the algorithm.
