All the more reason to not have them. Though email addresses? Are they demanding all pen-names too?
I simply uninstalled all their apps and deleted anything that I had ever posted which wasn’t completely irrelevant. I also deleted almost every picture of myself and prohibited people from ever tagging me.
This way I look like a normal boring guy who likes board games if you glance over my profile, but you couldn’t actually get anything to use against me.
It’s very Orwellian I guess, but it means I never have to explain why I’m not on social media.
It wouldn't surprise me that if in 10 years we all will need to have a minimal social presence to do routine things like travel.
