Yes, it does make me wonder if it is intentional!
There was a guest that Airbnb CS actually told me to report and block, but I had to choose 'they are being offensive' in order to block them, when that was not the actual problem at all. Apparently (confirmed by the Airbnb rep), the only way to block is if you choose that particular problem. You'd think they would want to know the real reason why. But the fact that the guest had created a new profile to get around a bad review (which stated that different people were using the same account) and trying to mislead me, didn't seem important.
By the way, it didn't make any difference. Neither the guest's original profile with the terrible review, nor her new, basically fake one, were removed and she has been able to continue booking with unsuspecting hosts with the new one. Both profiles say ID has been verified by Airbnb. It's a bit of a joke really.
