@Matthew285 yes, if a guest is breaking a rule then a host's only recourse is to remove the guest from the space. And then yes, the host (and the guest) will be able to write a review. The host will clearly write a bad review, but what kind of review do you think the host will receive from the guest??
(however, to correct a commonly held misperception, when you remove that guest, ABB will refund the rest of their fees for the time they do not stay in your house, regardless of your cancellation policy. So, many hosts endure rule breaking guests unless they'd rather have the guest gone than receive the rent $. And as mentioned above, a removed, rule breaking guest still gets to review you, so that factors in as well.)
It is much better to write your rules as a deterrent rather than believing that they will actually protect you.
The other thing to keep in mind is that your booking thru ABB is not a rental contract. But you are allowed to have a rental contract with guests and if you do so then you may have more recourse for pursuing the guest directly for rules infractions, but this will be outside of ABB.
