Sorry, I don’t get quite it, I guess. Palin’s Revere gaffe was on June 3rd. Since then, only one account tried to bring in any Palin stuff into the article and that guy seems to be just… out there. The other edits since June 3rd seem to have been the regular copyediting and removing of unsourced material. I don’t see the big concerted effort by Palin fans in the revision history.
