I'd say the time for your concern about your civil rights online passed about 20 years ago. IMO, it is a pretty naive man who would believe that repeatedly visiting child porn sites (I don't think anyone who has gotten to them "accidentally" once or twice has anything to fear) doesn't carry the risk of being surveilled online by government authorities. Same for online prostitution, violent and sadistic pornography, and all of those murky areas where at least some of the people invovled are being victimised.

Don't want to risk the civil rights violations? Then don't go to the sites.
