Hello @Regis-and-Christi0
Airbnb has at least for the last two or three years had a policy of trying to negate high risk guests from using the platform because of the risk of these guests partying/damaging your property and the attendant bad publicity and risk that local government will ban STRs in your area as a result.
Personally I am happy they are doing so.
Sadly sometimes good guests get caught up in their algorithm
Absolutely it is your property and when you take direct booking you can undertake the risk of accepting whoever you want. However if you want to use their platform to market your STR business, you need to play by their rules, whether it using their cancellation policies or accepting they will restrict high risk guests to minimise anti-social behaviour/partying/damage to your listing.
If you find their policies too restrictive, then there are other listing companies you can use and you can invest in setting up your own marketing channels and advertising to promote them.
