I've written multiple books and seen many types of piracy.
The most annoying is piracy that Amazon could prevent with the work of an intern. They've shown little interest in this.
Authors have little pull because Amazon is the only player for book selling. (I know there are other places to sell books, I've used them. Better to focus on Amazon for passive sales.)
It seems more complicated than that - Publishers (representing more authors), pseudonyms (and pluri-pseudonyms) etc. - but not dramatically so. A battery of people (human level intelligence) will check to validate the "upload" process, and automation aided.
Already now: what checks that John is not selling Jack's work? The mechanism is similar.
