I am sorry you had to experience that. Airbnb do have a policy in place regarding guests attempting to take you as a ` review hostage`, its called extortion. And sadly there are a few cases.
He never gave you the opportunity to recitify.
He never contacted you, you contacted him and he was verbally abusive in tone and wording.
You never listed his requirements as being in your premises.
Even if he had left a negative review, you can counter his review with facts on what actually transpired.
You can also request that a review be removed if it is not factual.
If he verbally threatened you with extortion of funds over a negative review. Message him and send him a synopsis of the conversation....` following on from our conversation, can I clarify that you require.........based on you stating........`. If he reiterates what he said in writing then that evidence for you against him.
Or he may realise that you are onto his thieving scam and backdown.
I`m also new ( had previous account, and I`m seeing a lot more of this kind of scam than previously years ago). And I think some folks actually target new listings, as they are banking on us, not knowing. I have only been re-opened with a new listing 2 months. And I already had a person attempt to encourage me to breach my own terms and conditions. She had zero reviews and yet worded herself in a way that said she was experienced guest. When I said no, she resorted to emotional manipulation. It was still a no.
If you do not have a co host , I recommend you get one, so you have a wingman to take some of the experience from your shoulders. Also as a woman, I do not have an image of myself on my profile, because I do not want to be looked upon as a potential soft touch based on my gender and age. Believe me, there are professional scammers out there. Good luck and be direct when you contact Airbnb. Bullet point all his actions and yours in comparison.
And you can cancel without penalties, if the guest is abusive or causing you fear, or making you uncomfortable. Wish you all the best, every guest is a learning experience.
