Preserving user privacy is difficult when detectingmore nuanced forms of censorshipSome forms of softcensorship might involve intentional performance degrada-tion or content manipulation. Detecting this type of behav-ior would require comparing performance or content acrossgroups of users, but such a comparison also implies thateach user must reveal their browsing history.
If you want to investigate whether content for a user was manipulated or performance was degraded, there may be no other way but to access detailed logs of their usage. This might raise privacy concerns.
Not only is personalization difficult to disambiguate from manipulation and censorship, personalization also makes it more costly to compare the personalized experience to some baseline value to determine if manipulation or performance degradation has taken place.
