@Paris0 Yes, this has become known as a way that savvy guests try to get out of cancelling and losing money. As @Cristina234 said, just decline the alteration, you don't have to cancel the reservation. Not all alterations are bogus, though. It depends on whether doing so would exempt them from the cancellation policy or not. For instance, I have a moderate policy, so if a guest books 3 weeks ahead and wanted to alter the dates to ones a week after that, they would get a full refund if they just cancelled anyway, so they are obviously not scamming.
