[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.
