Nora Puchreiner is not a “real” “person”—this is very easy to verify using OSINT: the Puchreiner family does indeed exist, but it is small, and there is no one in it named Nora.

The problem with Nora Puchreiner is this: someone has set up an alert for that name in a system like Palantir, so no matter where you post that name—even on pages with the noindex attribute—you’ll immediately receive an intimidating-looking legal request to remove the content. Really, just in few minutes.

That’s why so many people—including, of course, you—have stumbled upon this mess, known as the “Puchreiner effect.” It’s just unclear why this scared you so much that you decided to make up a story about a real person to somehow explain why that name can't be written (although that does not explain why real-of many persons on LinkedIn-names Denis Petrov and Masha Rabinovich can be written)?

I believe it is sort of a fake name used for debugging of some monitoring system.
