No… But i’ve thought about how easy it would be to implement in ebooks and pdfs (e.g. my daily newspaper i can download as pdf). I’ve thought about this when sailing the high seas.
It’s prevalent among pdfs downloaded from academic publishers (text listing the receiving IP address and/or institution running down the margins). I wouldn’t be surprised if it’s also done with hidden white text or in the metadata.
Most ebooks I bought recently come with a warning that the buyer’s data is embedded in the file to deter from sharing it online. TBF it cannot be hard to remove it but I didn’t bother to check how it’s implemented.

Is it a thing?
Yes, ebooks too. If you’re going to share those, learn how remove any identifying metadata. There are plugins for Calibre for this purpose.
Watermarking is definitely a thing. Whistle-blower have to think about that as well.
Yeah - was motivated to do a search :) https://www.lemonink.co/home#start-using
