I know of no business that regularly tracks the reputation of any _individuals_ in a database as part of it's regular business practice (the individual part is important) and that isn't part of it's model to disclose to involved parties. Uber would be a good example of someone that does this, but at least you can see a users rating at the time.

I never said it was unusual. I think you're honing in on the wrong thing on this thread - which is the presumption that people are disgusted that these tactics happen. I more concerned that they are actively tracking it in a "review style" database and the data is only access by a select few (which is the presumption here).
