Are undergraduate recommendation letters really sent to a specific person? And only that person reads it? I doubt it. I briefly browsed the organization's website, but I didn't find any verbatim copies of the documents they describe obtaining, so I can't confirm/deny this suspicion. I think it's known that the letters can be read by anyone at the University and Federal Law has stated for the last 40 years that students have a right to view these communications. Not only has this right been codified for at least a generation, every student does have the right to know what a school is recording and communicating about them. There's no (valid) assumption of privacy anywhere to be found here.
