It's a lot easier to Photoshop a mock-up of some options than to actually implement them. Fine-grained categorization of posts so that the feature could work is a pretty deep rabbit hole, regardless of how it was implemented. Additionally: * Filter-it-yourself doesn't do anything to address major societal problems like mass delusions about supposed codes,deceased politicians returning to save the day, etc. * Filter-it-yourself worked pretty well in the 90s on Usenet, when the signal:noise ratio was high enough to manually maintain a killfile. I don't think it's realistic on an internet with billions of users and bot networks.
