Blocking a guest from re-booking

[Shelly335]

I had a guest over the weekend who broke our house rules.  Our maximum capacity is 2; our loft is very small with only one bed.  She brought 3 in her party. I contacted Airbnb support and they worked with me and the guests ended up leaving.  I refunded one night's stay, just to be courteous.  She left me a 1 star, and stated a ton of untruths.  It was removed because she broke my house rules.  How do I block her from booking again?

If you answered would you host the guest again and said no, that should block them. Maybe call customer service to ask?

@Mike-And-Jane0 do you know the exact procedure for blocking a guest?
