Implementation of user chosen mute lists are coming for peakd so hopefully that helps (they do depend on people creating good lists that are also labeled well so that users understand the list and want to use it). If needed we could consider something like a statistically driven automated badge that indicates a user as a heavy repetitive commenter. Even perhaps possible to put that badge on comments. This gives an option to be made aware while not going as far as muting their experience. #ideas
