Hotel blacklists
Hotel blacklists are not yet as prevalent as other similar databases but seem to be the trend.
They aim to prevent abusive guests from staying in hotels.
Hotel blacklists are one effective way of keeping track of hotel guests who repeatedly and blatantly disregard house rules when staying in hotels.
This includes hotel guests who are abusive and do not treat hotel staff with respect. In the past, there really has not been a formal way of keeping track of these kinds of guests.
What happened was that the hotel management had to deal with these guests in their own manner and there was no way of spreading the word around to other hotels.
