I'm not going out of my way to make an exhaustive listing of these things, so I've probably missed some currently existing systems that do this. And certainly until we come to a clearer understanding of the boundaries as a society, more people are going to have more bright ideas for this sort of censorship that seems to solve some short-term problem, while remaining blind to the long term disaster allowing such things will cause. I would be willing to bet money that within a year of the "publication" of this essay, to the extent this is "published", at least one more system will be proposed based around this idea. When it does, I hope you can recognize it.
