sneaky guests still booked after I declined them

[Azzuri0]

I have instant booking option on my listing, but its instant only for guests with previous positive review, 2 days ago I got a reservation request from a person that wants to book my place for their group of  4 people, this individual doesn't have any reviews, no description, and some crazy fake picture. I declined the booking explaining I don't accept it bcs of the reasons I just mentioned,  but today I got an instant booking for exactly same dates, for 4 people, from the same city and even a weird message how they are picture perfect guests. I am 1000% sure this is the same group that I already declined but because someone from that group already has a positive review I couldn't decline instant booking this time, and although the guest has postive reviews, there is no description of him, and the profile picture is of drugged up Macaulay Culkin. So what can I do to cancel this group and not get penalized from airbnb?

@Azzuri0   I would contact airbnb, inform them that you believe you're being played, ask them to look at the message stream, and cancel the booking on your behalf without penalty.
