It's hardly any secret that Airbnb "support" is rarely supportive. Especially when it comes to things like trashed houses or damage. Forget "AirCover", it's a marketing tool, and little more. But if you're listed on other major platforms, I believe you'll find that they also are rather brain-dead when it comes to host support.
So, if you can't expect support, then you need to take matters into your own hands. My advice is always that the most effective remedy is prevention.
First, turn on all filters for "instant book" or turn off instant book altogether.
Then, when somebody wants to book it, first check their profile and history. That tells you a lot to begin with.
Then, ask a few benign questions to solicit a response "Hello <name>, thanks for your interest. Are you coming for golf? We are near 3 golf courses".
Nobody mentioned golf (or whatever topic you choose), but this is a friendly way to get them to tell you more about themselves and why they're coming. Their answers (or lack of them) can speak volumes about their character.
And if they booked for 1 person, you need to ask if that's correct. Just one? really? The answer can tell you a lot.
"Me and my buddies really like your place" - that doesn't really answer the question, and "me and my buddies" is generally a red flag. If they have no review history, or if their history is checkered, you may want to suggest a cheaper place - "I believe you'll be more comfortable with this place, which is less expensive and closer to the strip - airbnb.com/rooms/xxxxyyyyzzzz", "I wish you a pleasant stay, wherever you end up". Declined.
"We are having our annual family get-together - Me and my husband (40's) , my father, mother (70's), my brother and his wife (40's). We do this every year.". She was direct, concise, has a good review history, and clearly has nothing to hide. Approved.
I should also mention that it's wise to keep your prices a little bit above your nearest competition. Guests who seek that which suits their interests over price tend to be happier and more conscientious than those who are seeking whatever is the cheapest. Let your lower priced competition have them. When they're all booked up, you'll be the only game in town.
The above is no guarantee, but I think that over time, you'll find that the number of bad experiences - and bad reviews you receive - will diminish significantly if you follow these simple steps.
Since you really have no recourse through "support", this is really your only shot at avoiding these nasty surprises.
Good luck and happy hosting.
