Hello @Stay-Together0
I have never had this happen in four years of hosting, but then I am an individual host rather than a property management company so likely to attract a different type of guest.
The best way to warn your future hosts about problem guests is to leave them an honest review.
I am not sure how your guest only raised issues with Airbnb after the 14 day review period passed. Surely Airbnb says they need to do so within 24 hours of their arrival?
And with guests that threaten bad reviews if they didn't get a late check out, I hope you are flagged this with Airbnb and mentioning this in your reviews of these guests along with marking down to a maximum of three stars, so they can't iB with future hosts.
