I have always been a bit wary about those IB questions. Many guests do not answer them (and this has always happened in my experience), but it's not just non-communicative guests. I've had great guests with great communication that, when asked, told me they never saw them.
On the other hand, I've had guests who have obviously seen them by the way they phrase their messages to me (literally answering the questions point by point). So, they must be visible, right?
I am guessing they are visable, but in a way that it's easy for many guests to miss them, i.e. not obvious enough.
