Also known as: open group
A group in which any article reaching a server propagates without review, which describes the large majority of Usenet. With no gatekeeper, filtering falls to the reader through killfiles and to the administrator through spam-filtering software such as Cleanfeed. The absence of moderation is the main reason open groups filled with automated junk once bulk posting became cheap in the mid-1990s.
