A product design manager for Facebook wrote an op-ed for today’s New York Times on trolls and the tendency for anonymity to encourage uncivil behavior. She proposes a variety of methods — some used here, including registration and some moderation — to encourage more civil comments on websites. It is interesting to read of legal efforts to force disclosure of people who make unflattering comments in an era when anonymous speech in the form of huge corporate expenditures on political races has been given broad protection.
