@James1560 I'm sorry that your efforts were unsuccessful here, but before this thread fizzles out could you please post the review you left (or whatever you remember of it)?
The actions of your guests were reprehensible, and you deserve an opportunity to express this in your review. But for hosts who have been the victims of these bad actors, it's important to recognize that publishing a public statement about a person carries a serious legal responsibility. Even a single word can push a negative review over the line into defamation, and that's where it gets really problematic - even when you have good reason to believe that someone has committed a crime, you don't automatically have the right to publicly call them a criminal.
I believe in honest reviews, but here are the top three things that should never be directly mentioned:
1. Drugs. It's one thing to qualitatively describe a bad behavior, or to state that the guest broke your rules. But once you make a suggestion that illegal activity occurred, especially when you didn't witness it, you're giving Airbnb (as the publisher of the content) a libel risk that it does not accept. ("Drug paraphernalia" is also a no-go, especially when it makes something relatively benign like nitrous oxide canisters sound more like syringes and crack pipes).
2. Sex. Any insinuation of intimate, behind-closed-doors activity - no matter how unpleasant its impact on the home environment - is bound to be taken as a violation of the guest's privacy
3. Bodily functions. Vomit, feces, blood, urine, and other excretions also fall under the category of too-intimate-to-mention. It's sufficient to say that the guests left an unpleasant mess or failed to clean up after themselves, without naming any bodily fluids.
Airbnb doesn't explicitly state any of this in their vague Content Guidelines, and they don't tend to give you a specific reason for removing a review. But if any of your word choices brushed against one of those three things - which others have warned you about here - I could have guaranteed you that the review wouldn't be up for long.
