TSA is not a business, it's a government agency. There are things businesses can do that the government is prohibited from because there's one very big thing the government can do that a private business cannot: deprive you of your freedom.
However, that doesn't happen. So, we're stuck with an ineffective bureaucracy that is a waste of time, money and resources that labels itself "security".
I'm saying that you keeping a notebook with information on people who have offended you is much different than Amazon or the government keeping a list of people who have offended them.
