This is an interesting use of the web by Margaret Cho. She's been getting a slew of awful email since her statements at a fundraiser were taken out of context (her opinion of the selected transcript), so her webmaster posted them all, with their original email addresses. The ones that notice they've been publicly shamed have recanted, many invoking their Christian teachings (but why did they send such hateful messages in the first place?).
Of course the difference between this page on Cho's site and the NRA's blacklist of people to avoid and harass aren't that different, but this is the first time I've seen a celebrity use their notoriety to bolster aid online.
