off platform violation letter

[Gigi155]

Today we received this letter ~ We’re reaching out because it appears you’re using your listing The Broken Arrow Camper Arizona Joshua Tree Escape to communicate privately with guests pre-booking and potentially book off of Airbnb.

But we have never accepted an off site booking or had any inquiries regarding one, so I am wondering if a nasty neighbor is trying to sabotage us? Or a past guest is lying? I am worried and confused. Our rental is  not in a busy town it is pretty much in the middle of nowhere so it isn't bothering anyone as far as we know. 

Help!
