Did you have pirated material in OneDrive? Did you pirate Windows, Office, or any other Microsoft software?

I'm thinking content scanning or Microsoft Account telemetry.

I don't think that this matters as much unless you've shared it & Microsoft got some sort of DMCA notice.

By any chance, did you have child nudity (ex: photo of child bathing, etc.) on your OneDrive? If so, I wonder if PhotoDNA picked it up (see https://www.neowin.net/news/man-arrested-after-microsoft-fin...).
