OK, before things go completely off the rails....
It would be a lovely world indeed if no one ever attempted to scam a hotel (or other business) out of money by claiming something happened that didn't, and seeking compensation for it. Unfortunately, that's not the world that we live in.
I've read of people faking accidents and injuries in hotels and demanding that their stay be comped, or suing the hotel operator. I've read of people purposely damaging things in their room, and then complaining that their stay was ruined because that thing didn't work, and that they want their stay comped. The stories are endless.
Hotels must protect themselves against these and other kinds of losses, and they have a number of ways that they do it. One of these ways is to maintain a record of any compensation given to a guest, so that if that guest's name turns up four times in a week at various resorts and theme parks, and then the same thing happens six months later, they see the pattern and know that the guest may be up to something. The criteria for giving that guest compensation are going to get a lot stricter.
If you're Mr & Mrs Nice Guest, and you complain at a resort because the toilet in the room above overflowed and ruined some of your clothes, and you get 2 nights of your stay comped by the nice manager, are you blacklisted forever and will be verbally abused and snickered at and given a bad room every time you stay at WDW? Of course not. That's ludicrous. That's not why these records are kept.
Actually, it's a plus for all the honest guests that a compensation list is kept. If a hotel's not making its profit targets because they're constantly giving comp nights and free meals and monetary awards to scammers, who do you think pays for that? Not the hotel company. You and I do, in increased room rates.
Again, this is standard practice in the hotel industry (and many other businesses), and has been for a very long time.
