Right. So let's get this straight..
As @Helen3 correctly points out, UK (and indeed, many other countries) government legislation clearly states that people SHOULD NOT be asked to provide evidence from a medical professional to prove that they don’t need to wear a mask.
Yet Airbnb mandates (complete with threat of deactivation)...
If you have a medical condition that prevents you from wearing a mask you will be required to provide documentation from a medical professional confirming this exemption. You will then be required to notify all incoming guests prior to booking.
If a host is unwilling, or fails, to disclose this exemption to guests before booking, the listing may be deactivated until this policy no longer impacts them or is updated.
Meanwhile, hundreds of thousands of guests have been routinely gifted (frequently unwarranted) full refunds for over 6 months now, by being permitted by Airbnb to simply "attest" to the fact that they or even one of their unnamed, unregistered (alleged) group members were sick with COVID.
Also, huge numbers of hosts have been awarded the Enhanced Cleaning Protocol badge, by simply "attesting" that they are following Airbnb's preposterously convoluted and contradictory cleaning diktat, which every dog on the street is fully aware that in reality, just about nobody could possibly be adhering to in full, to the letter of the stipulations.
Yet experienced, trustworthy, highly reviewed and rated hosts with a long and proven track record of loyalty and commitment to Airbnb, are being forced to produce medical documentation for exemption that will be next to impossible for them to get hold of, or risk getting booted off the platform. Why so? What's the issue with medically-exempt hosts simply being allowed to "attest to the facts" too? Because their word can't be trusted - is that what Airbnb are trying to insinuate about their root and branch hosts??
This stinks to high heaven.
