Many of you wrote to tell me how you'd like me to deal with trolls in the future. Your language was often lively but clear. It was suggested that I follow the long-standing rule of the page: "Comments and posts that are designed purely to attack others and/or drive away readers are subject to deletion."
Perhaps we can also do a better job of not engaging with trolls when they do come around. Most sources I've read about this suggest trolls are seeking attention.
I've also gone back to yesterday and cleaned up some of the mess. Occasionally that means some non-offending comments end up zapped as part of a longer thread. I am sorry for the inconvenience.
