Hate to say it, but as you know, you did all of the wrong things - didnt do anything within the timescales, didn't comment publicly on their review of you, and you even wrote them an ok review...etc...
So there is no warning to other hosts about this guest.
Not a lot you can do - I doubt AirBnB would even investigate at this point in time as you have left it so late to even query their review of you.
Perhaps drop you price a bit and get some bookings through and good reviews - the others quickly disappear.
