Good examples. Plus Usenet too. All of the above work by permitting the end-user to moderate to the extent he / she wishes, or not at all. I had kill-lists for Usenet, I can DNS-blacklist websites I never want to see, I can grey-list or silently drop troublesome e-mailers. No-one makes the choice as to degree or method except me and yet it works.
