At one point I figured that I might need it to seem normal sometime in the future.
Traveling to the US last year I'm glad I did, passed through the border checkup much easier than my other privacy loving friends who deleted thei social media accounts.
I also kept my gmail address even though I moved to fastmail. Mostly use it for signing up to things and unimportant stuff, but it sure was handy at the airport.
I guess it still exposes some of my life, but it's not like I can ever become anonymous again, since they never delete anything.
