I am so glad that your direct marketing has been paying off. That's great news!
Yes, I also find it super annoying that they have taken away the 'would not host again' option. There are certain things we don't want to spell out in the reviews. That doesn't always mean the host is being dishonest and not warning others, but some things are better left unsaid.
I once hosted a couple, who were actually exes, not an existing couple. I didn't even know initially that the two would be staying as the lady booked for herself and later asked if her 'friend' could join her.
Turns out they were having a massive crisis and, after a tense two or three days, it came to a head and may, or may not, have involved violence. The lady left, the guy (who was not the booking guest) stayed, and the whole thing was deeply uncomfortable for me and also a bit awkward for other guests.
Am I supposed to go into detail about that in the review, or even mention in a vague way that they were having a relationship breakdown? Probably, either guest would have been fine on their own or in different circumstances, but I wouldn't want that experience again.
