People who sell mailing lists, that they believe are copyrighted, seed their lists with a name and address that is only on the mailing list that you purchased.
If the unique person on that list receives another piece of mail, they know that that list buyer sold, or lent, the copyrighted mailing list to someone else.
Trump, it’s been reported, is employing similar cleverness to catch his leakers.
Intel is being passed with unique seeds in each report. If a story leaks and it contains the seed, then they’ve caught their leaker.
He reminds me of the professor who was confronted by 4 students who missed their final exam because they were out drinking all night.
They concocted a story about a flat tire and pleaded with the professor to let them take a make-up exam.
The professor agreed. He sent them to 4 different rooms with a test that only had one question.
“Which tire went flat?”
Some people just can’t be outsmarted.
Trump is one of them.
