@Heather1086 “….just don't want some weird retaliation on the platform for reporting them.”
Any time you mix sketchy guests and Airbnb together, you are at risk of some negative outcome. Add in security cameras (pointing at hot tub no less) and the risk increases. Proceed with caution, and thoughtfully, if you wish to avoid triggering the guest to claim a privacy violation over the camera issue, which will result in Airbnb suspending your listing. It happens all the time, even when we follow the rules and disclose properly. Airbnb snap suspends, without even getting the host side of the story or considering proper disclosure was made. In no way am I suggesting you shouldn’t report or honestly review the guest, but do proceed carefully to best avoid getting the short end of the stick.
Thankfully, it doesn’t look like there was much, if any, damage. Note that you have 14 days to submit a claim now that Airbnb has updated the process. Unfortunately, this is still within the review window.
Refer to the review guidelines when composing your review, to be sure you write one that won’t later get removed.
