@frank A friend some twenty years ago phrased it as "I don't mind that you can find out a lot about me online, but it has to take effort." There needs to be some friction: if you want to know more, that is possible but you have to spend some time digging and reading. To me this relates to the role of social distance and esp asymmetry (I can know a lot about you, even if you don't know I exist), and these days to 'reverse Turing testing'. Friction may reduce the social distance and the asymmetry the 'knower' feels because of their own effort investment. Longer time visibility may also serve as proof you are human in these algogen times. That said, if I don't want something known I go for better opsec/infosec in parallel to my more public activities.
