I kind of doubt reverting changesets would work out very well. Reverting a changeset becomes more difficult as time goes on and things in that changeset are touched by other users. Then you get into conflicts and other odd situations that are hard to handle.
I did some remapping in LA from TIGER 2011 and documented my approach: http://ksmapper.blogspot.com/2012/03/remapping-using-tiger-2011.html It was not easy but allowed me to clear out a fair bit of dirty data. It was mostly residential roads so I didn't have to bother with relations and such which helped. I kind of burned myself out on license remapping before the April 1st "deadline" and haven't done much since. As for determining exactly what blars did, I highly recommend the "deep diff" service that Ian wrote: http://osm.mapki.com/history/ It is also accessible from the OSM Inspector license change view by clicking on the clock after selecting a dirty object. Without some object IDs it is hard to say exactly what blars did. If you have some specific examples, select them in JOSM and hit CTRL-SHIFT-I to open a browser window with a link you can send to the list. A lot of what I saw in LA looked like legitimate mapping to me. He was active before the TIGER import so there is a lot of his original data still around.
