As I understand it, the Admin Moderator will remove keywords at the request of the original poster (which is Hair, I think), in a freepmail. Some dodo started a stupid thread, and lots of folks were adding insulting keywords, and they got removed.
No question that people with ping lists should always request folks permission to add them to the list. A good example is mhking's high volume Black Conservative ping list, which averages 10 or so pings a day, and only puts people on who request it. At least the lists you are talking about are not as bad as the guy who put together a super ping list, apparently including all members of FR, you may remember he pinged once or twice, then had his head handed to him.
