I assume you are referring to instant bookings?
As far as I am aware, there was a box that guests had to check to agree with house rules (doesn't mean they actually read them. We have all skimmed past T&Cs and just ticked the 'I agree' box). Not sure if that is still the case though as I stopped using IB a few months ago.
I insist that all guests confirm with me via the messaging system that they have read and agree to the full house rules before I accept their booking (I used to also do this as soon as they booked, if I used IB). I even have an 'Easter egg' question in there as I found that a lot would say they had read them when they actually had not.
If it's an IB, you get 3 x penalty free cancellations per year if you think that a guest will break your house rules, throw a party or that you simply feel uncomfortable with them. After that, you have to request a penalty-free cancellation from Airbnb CS.
