Yeah it started commercially about a decade ago from what I can tell. Now it’s probably part of every ebook. It’s just a little code. Cheap and easy if you want to track leaks and/or pirating.
Old spy craft thing. Disseminate 12 copies of a doc, each with a very subtle difference. If that doc pops up somewhere it shouldn’t, you know where it came from.
It’s definitely still useful and easier to do now too. SpaceX and Tesla both allegedly use it to catch leakers. It’s usually done now with whitespace and/or invisible characters.
Also run spell check. Specific misspellings are another tracking method.
Reminds me of “paper street”
Is that why they’ve been more prevalent? Just thought terrible editor not intentionally making books worse.
why don’t people want to pay full price for ebooks
It’s a spy/security thing, never actually heard of it being used for something like ebooks.

LOL, probably not so useful in the digital age.
