Use user-defined kill-files (although if you want to publish them you can, in case someone wants to copy and modify for their own use, or they might decide not to use it at all if that is their preference). Allow anyone to comment and to reply to anyone but remember someone might set up a kill-file to hide messages from someone who does not want to see your messages (whether or not you are an administrator of the service, or police, or whatever). We need more freedom of speech, not less. But, freedom of speech should not mean to force everyone to listen to you if they do not want to listen. (Kill-files could also be based on whatever criteria you want, not necessarily only based on the author of the message, although that would probably be the most common case.)
