I've had an issue with a previous guest stealing from me. I didn't notice until I was preparing the property for the next guest. As everything looked in place when I went to pick up sheets and towels etc, and the house had been tidied (except a few cigarette butts in the garden), I gave a good review and moved on. It wasn't until after I'd left the review and 48 hours after checkout that I had noticed the game was missing.
When preparing for the next guest I did a quick vacuum of the loungeroom and noticed one of the Guess Who pieces on the floor. I went to replace it, but the game was missing. They were only my third guest and I've already been stolen from.
My understanding is that now that I've left my review and 48 hours has passed, there is nothing that I can do apart from sending accusations of someone stealing a $10 board game. If I accuse the thief, what if they revisit and trash the place while I have no tenants?
How can I covertly warn other hosts about this thief (or his travelling companions) without risk to me or my property? Is there anything I can do? The police will see it as heresay, and the AirBnb reporting window has expired.
