Once you support delegating your killfile to other people it no longer functions the same as each user having their own. And FWIW, as an example, here on Hacker News, many of us have showdead turned on all the time and so while I am aware of the moderation put in place by the site, I actually see everything.

Also: frankly, if there were someone willing to put a lot of effort into moderating stuff Hacker News doesn't--stuff like people asking questions you can answer in the article or via Google--I would opt into that as I find it wastes my time to see that stuff.

And with delegation of moderation, I think it will start to feel like people voting for rulesets more than a bunch of eclectic chaos; if a lot of people agree about some rule that should exist, you will have to decide when you make a post how many people you are willing to lose in your potential audience.
