Okay. I'm not surprised by that at all. Once upon a time, it was possible to have a review removed for being untruthful/in retaliation for something. It happened to me and it was actually the Airbnb CS rep's suggestion. I was calling about a technical issue to do with my star ratings. The rep, who was not robotic at all, spotted this complete outlier of a review from a few months before and asked what happened.
I explained the the guest had not read the listing/house rules properly, even though she claimed she did, that I had needed to mention to her some cleanliness and damage issues (never even asked for money, just asked her politely to be more careful) and to ask her to stop messaging me at 2am, and after that she turned nasty.
The rep read through the communication and also checked my listing/house rules. He agreed that the review and ratings the guest had left were lies and removed both. That was back in the day though...
Since then, a couple of things have changed. Firstly, see @Anonymous 's response above. A couple of years ago, Airbnb added that clause to their review policy: Airbnb doesn’t mediate disputes concerning the truth of reviews.
Hence why the rep was not interested in the text messages. This, no doubt, was to cover themselves and probably also to save time by not getting involved in review mediation, thereby leaving users wide open to abuse, revenge reviews and scammers. Of course, a guest can be on the receiving end of this, but it's more likely to be a host who suffers and, it's easy for a guest to start a new profile once they receive a bad review. It's not so easy for a host to delete everything and start again.
The second thing is that, when the pandemic started, Airbnb laid off a lot of its experienced, knowledgeable frontline CS staff and replaced them with outsourced reps who have very little training, next to no authority to actually do anything, and read from a script, hence the robotic responses.
