In the last seven days I needed to dive really deep into searching a host in Berlin, updating the site several times a day.
I saw at least three fake ads, which were luckily taken offline, but it still took Airbnb some time.
The informations in this listings were something along the line,
"don't book this apartment [...] just get in touch, because dates are not synchronised with calender."
pictures were for ridiculous fancy apartments to really low prices.
How and where to point out such listings?
