Usenet Death Penalty


   [Usenet] 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.
