@Fleta0 Not reviewing does not affect your Superhost staus or anything else.
But failing to review bad guests is a real disservice to your fellow hosts. This is how bad guests get to continue to go on to behave badly in other Airbnbs. You need to warn other hosts.
I have often read hosts being worried about some physical retaliation for a bad review, but I have never read off such a thing happening. Guests aren't going to come back and burn down your house because they got a bad Airbnb review.
You can be general in your review, rather than specific. It's always more helpful to other hosts to mention what the issues were, but if you feel you can't, something like "Due to numerous issues with this guest, I would not host them again" would be sufficient. Then give them low star ratings for following house rules and cleanliness and mark "Would not host again" (Guests cannot see anything but the written review).
And learn to vet your guests better. You can require that guests have a profile photo, for instance, and if you don't feel okay about them when they message you with a booking request, decline the booking.
