That's where it gets even more confusing. Yes, these requirements have been updated on the site for EU users, but that's because Airbnb has been forced to do so by the EU Commission, on foot of recent Airbnb-specific legislation.
However, hosts (including homesharers) in many other countries around the world have had their payments witheld until they signed up for an Airbnb business account too, once they pass the earnings threshold (AUD15k, €9.3k or local equivalent). I'm going to try and tag Australian hosts, Lisa and Jayesh, in here, who have had personal experience of this.
It's worth noting too, that hosts worldwide - with the exception of US, China and India - also contract through Airbnb Ireland, which is obviously subject to all EU rules and legislation. It's unclear at this point if/how non-EU hosts who come under the umbrella of Airbnb Ireland are affected by the rulings, but for sure, Airbnb did amend several policies recently in those countries too, that they were compelled to amend in Europe by the EU Commission (how pricing is displayed, being just one). So from the evidence so far, it does look as if whatever changes come into affect for EU hosts, are also being applied to all non-EU hosts who transact through Airbnb Ireland.
As regards hosts with business accounts on Airbnb being legally obliged to clearly display their business details - including phone number - on their listings, I'd imagine that would be governed by the laws in each specific jurisdiction, but I'm not 100% sure on that, and trying to get straight answers from Airbnb on the matter - or any matter - is like getting blood from a stone
