Well it kind of makes sense if you believe people are generally going to follow social norms and not make false accusations for no reasons.
Like, all you have to do in a crowded theatre is shout "FIRE", and everyone acts as if there's a dangerous situation and everyone is subjected to being forced out of the theatre based on a single unsubstantiated shout.
Or if you put your mind to it, there are any number of false, anonymous allegations one can make with large asymmetries between the effort to make the allegation and the effort required to clean up the situation.
