The first time I tried to use Airbnb, they confirmed my reservation and charged my credit card. They then texted me a few hours later insisting I upload a profile picture or they would cancel my reservation. I didn't, and so they cancelled the reservation. I was just trying to book a cottage in my local area, so I tried to exchange contact info with the host through the messaging system, but they filtered out our phone numbers then presumably shadow-blocked us from further correspondence.

I have no sympathy for Airbnb.
