They do, and some of the information from at least one such hotel group was picked up by a resourceful third country/foreign government that knew which US airline-rate-users and USG-rate-users were repeatedly flagged as trying to bring suspected prostitutes into the hotel rooms. And in at least one case, a US diplomat’s spouse was falsely suspected of being a prostitute for no reason than being part of an “interracial” couple and that too ended up being in there.

As I said earlier, if you have a legal hook to get this kind of information from hotel companies, doing so can lead to some entertaining reading at times. I really don’t mind what hotels or airlines think of my due criticism of travel service providers as long as I get my chance to get in my due criticism in an appropriate way and I get what I paid for. To those travel service providers who aren’t entirely professional in their handling of customers, I may come across as a difficult customer at times. But as someone who has spent many thousands of nights in hotels and on the proverbial road, I also know when something is off with a hotel stay. And then I find myself doing a public service and provide duly critical feedback in an appropriate way.
