Sorry @Rebecca181, just seeing this now - still no notifications for me when I'm tagged..
This comes as no surprise whatsoever. It's always been Airbnb's standard policy to re-house disruptive and destructive guests with unsuspecting new hosts, but at least in @Inna22's case, it appears that they're willing to uphold her cancellation policy. In the vast majority of previous similar instances that I've heard and read about, the offending guests have been fully refunded by Airbnb - invariably against the hosts' wishes.
With the current media spotlight on Airbnb though, it really wouldn't be helpful PR right now for the company to be caught red-handed, penalising hosts (financially or otherwise), for cancelling either upcoming or active bookings, from guests who they have strong reason to believe have nefarious or criminal intentions.
So if they have any sense at all, they'll play nice with hosts, at least for the foreseeable. There appears to be a sudden epidemic of "If you have a juicy Airbnb story to share, contact this reporter at ******"-type notifications popping up all over the place recently, even in publications and online outlets that were previously very blatantly and fiercely pro-Airbnb - not something I've ever seen before (and I think it's fair to assume, it's probably not puff-pieces or gushing testimonials the newshounds are sniffing out - nor that there'll be any shortage of aggrieved and disgruntled Airbnb users lining up to spill the beans on their own nightmare experiences)
Funny enough, on the very day the news of the Orinda tragedies (and the Vice scamming article) broke, we were just discussing these exact issues, on a thread about the Airbnb Guest Blacklist FB group being shut down - and relating how Airbnb had been rehousing rogue guests with unsuspecting new hosts even after the Blacklist Group mods had provided irrefutable proof to both Airbnb and the unsuspecting host whose home had been targeted for massive parties.
Interesting to look back on that thread now and see that, despite Airbnb's very loud and very public gung-ho "zero-tolerance for party-houses" protestations, their reassuring words, their "exciting updates" and their placating, damage-limitation press releases... the truth is, sweet FA has changed, from that day, to this.
