Software can/will determine if it is the same writer in a few seconds. No need to read the drivel.
Nah. It presents the same problem as the textual analysis of St. Paul: The Harper Lee who wrote “To Kill a Mockingbird” is the same person as the Harper Lee who wrote its sequel, but that person has changed much over the years. If any software recognizes it as the same person, she might as well have died fifty years ago.
