Here in Germany there's a popular company called SCHUFA (https://en.wikipedia.org/wiki/Schufa) which collects (and sells) data about (non)solvent people since almost 100 years.
Thanks to law, one could already ask in the past about one's score. Thanks to GDPR, nowadays, they have to publish a much more detailed report of what they store about one. And it's really scary: It's written that I lost some scoring because I moved from a smaller building to one with more then 8 tenant parties (flats). So literally, I moved from a smaller house to a bigger one and now I am less creditworthy.
Yeah, I asked a similar collector of data in Czech Republic about the data they held, and they refused to provide details they based their scoring on, but provided me my historical scores, and it was basically a reverse of how my financial situatuion was during the years they provided scores for. As I gained savings my score worsened, and it was best when I had nothing.
One can only wonder, what that secret algorithm looks like. :D
It's sort of weird that some entity makes up some seemingly random scores about you, and other companies/institutions use those to judge you. That's quite a bit of power.
