Usenet Death Penalty

A sanction against sites that habitually spew Usenet spam. This can be
either passive or active. A passive UDP refers to the dropping of all
postings by a particular domain so as to inhibit propagation. An active UDP
refers to third-party cancellation of all postings by the UDPed domain. A
partial UDP is one which applies only to certain newsgroups or hierarchies
in Usenet. Compare Internet Death Penalty , with which this term is
sometimes confused.
