It is also common for authors to misspell names (proper nouns) in an attempt to determine who leaks docs (and to force non-matches for FOIA requests).

If you want to fingerprint text you can also do it by small insignificant changes to text which doesn't change the meaning.

If you have a number such locations with alternatives then you can make a number of identifiable versions by combining alternates.

Random side fact but this was also a thing map makers did back in the day. Including fake towns. In that way they could identify who was stealing their work.
