A trap set for spammers. To set this trap it is necessary to develop a Web page which contains a large number of email addresses. Such a page attracts the attention of a spammer's address harvester. Hidden within the page are some addresses which are associated with a mail server with an inordinately slow response time, usually numbered in days. When the spammer attempts to send an email to the server nothing happens and the spammer's mail program hangs. See also Web trap, flytrap, and spam magnet.
