I was tempted to vote Yes because some social media I use gives me the chance to be undestood in a way people don't usually do offline, and to exchange opinions about stuff no one I know cares about. But honestly I don't even have to use certain social media for it to bring me pain. The data privacy of many of these things is so abysmal that you can go your life without ever visiting the website but they still have information about you, gathered from your friends who shared e.g. their contacts with Meta.
I also think it really depends which social media we are talking about. The culture on twitter, for example, is an amazing example of why you should "live unknown".
