Airbnb should just be upfront and tell customers they need to assume they are being filmed at all times. There are cameras now the size of a grain of rice, this issue will never go away, the cat is out of the bag.
Maybe this is not bad advice. Kinda like "don't post any pictures on the internet that you wouldn't want your grandma to see" or "assume your employer is reading all your e-mails". But still, it is a massive invasion of privacy and there should be some recourse for the victims/punishment for the perpetrators.
