No moderation means it will be overrun with trolls and spammers. This is true of any discussion system. Once you grow beyond a certain point, typically a few dozen users or so moderation is necessary to avoid having the signal to noise ratio drop so low that all of the quality people leave.

I remember reading about Parler having that exact problem. Because of the "no-moderation" aspect, they were being overrun with spam and pornography.
