@Huma0 There was a post here maybe 6 months ago where a home owner had found out that someone had listed his property, which was actually for sale, using photos off a real estate site. The home owner wasn't a host at all. He reported it to Airbnb, who said they would look into it, but didn't take the listing down, even though he explained that the calendar appeared to be booked and guests would arrive to find there was no Airbnb rental there.
I don't know what became of that case- I recall that after many posts on that thread with many responses, the OP never came back to let us know how it all worked out.
And I'd also read other similar stories here from home owners whose long-term tenants were listing the property- some of them not just renting out a spare bedroom, but turned out not to be living there at all- just listing the whole place on Airbnb. And of course, because they were long-term tenants, at least on paper, the home owners were going to have to go through a lengthy eviction process to void their lease. Meantime the places remained listed.
Sure gives the lie to Airbnb claiming they are going to verify all listings to make sure they aren't scams, where even when what are clearly illegal listings aren't removed.
