While I don't agree that reddit should be judged by the most terrible content on this site, much more could be done to dissuade people from inhabiting its darker areas. How about disabling custom CSS/images and comment gilding on a per-sub basis? Presumably Reddit will need to flag offensive subs anyway (if they don't already) so that future advertisers' content isn't associated directly with them.
