Repeatedly posting the same message to Usenet newsgroups over and over again. Usually the poster makes minor changes to the post to prevent bots from canceling the messages. Spew is most commonly spam as the message is void of any new information. This may be against the TOS of most Usenet Access Providers. It is imperative to the poster that any message repeated has more of an intended purpose than attention to non-topic non-critical aspects of the Usenet newsgroup.
