You do have a point about guests seeing hosts photos, but hosts aren't allowed to see guest's photos until later.
As for call centers, in live in Alaska, so I have issues getting a hold of a US based customer service representative during regular Alaska business hours. Several call representatives overseas have spoken to me in a condescending tone, which I really don't appreciate (this may be because of the language barrier-not sure). I never have an issue with "tone" and friendliness" when I get to talk to someone based in the US (of course, I can never be absolutely sure where the CS rep is based).
On another note, I had a guest just recently call me a discriminatory name through the Airbnb message system, and even after I reported them, they are still allowed to still book through Airbnb.
