One journalist asked Tinder for all the personal data it had on her, and the 800 pages it got showed her how much it snoops on her.

I hope that, after further thought, she decides to advance beyond "How sad" to "No way!"

The evidence comes from Tinder, but I'd expect it to be typical of services that identify users by name. That's why I call them "disservices," and don't use them.
