Email addresses included in, or comprising the entirety of, a Usenet
message so that spammers mining a newsgroup with an {address
harvester} will collect them. These addresses can be people who have
offended or annoyed the poster, or who are included so that a spammer
will spam an official, thereby causing himself trouble. One
particularly effective form of spam bait is the address of a
{teergrube}.
