The unit that caused the biggest problem was listed on 2+ sites, so it is unclear which guests came from which platform. The person previously renting (an owner) ignored multiple requests to stop and only stopped when a fine was introduced. In the NYC market these situations can be very profitable so it is in the renter's/owner's interest to break the rules as much as they feel they can get away with until the equation no longer becomes profitable. This is how condo boards fight the situation -- the fines have to be heavy enough that it impacts the profitability of the entire concept. The condo board is in a position to put a lien on the unit for the money owed, so owners can not ignore the rules without potentially severe consequences.
