To come back to my NNTP example: Back in the day, servers were not banned by admins, individual users were killfiled (essentially a filter) by other individual users, meaning that if you really disliked someone, you would get rid of their output - without denying anyone else access to their musings, related to the topic at hand or anywhere else. It was a more civilized time. Today, server admins ban other servers for random issues. Users do not use the built-in killfile-esque blocking method, but instead go and complain to server admins (who then are incentivized to use massive action against other servers). This obviously is not an environment that will lead to societal harmony.
