Either get serious about your privacy on public networks tied to your identity (see facebook privacy checker: https://www.facebook.com/help/443357099140264/ ), only use 100% anonymous public networks (see reddit: https://www.reddit.com/ ) or stick to a 100% private social network, like I've done (see select: https://mailchi.mp/231daaf5ccef/select-03 ).
