I have another solution. I look normal online when filling out information. I use Facebook, whatever.
But whenever possible, I lie. Different name, birthdate, every question about "favorite pet"? A lie. "They" have tons of data on me, but more and more is wrong. Let it leak.
I use my password manager to maintain unique answers to all of the useless verification questions about pets, movies, teachers, etc. Only way to scale it.
Then this is something for you https://shop.digitalcourage.de/themen/ak-vorrat/lichtbildaus.... Either get it online, or buy at events like Chaos Computer Congress.
