> Even without access to such a tool they could simply...retype the text themselves?

There was a story I remember hearing, I think from an older student during highschool or during college from another student's highschool, where some kid was cheating by copying a hand-written paper from another student, and the paper had two names on it. They had put their name in the corner then just blindly wrote all text on the other paper, including the other student's name.
