sporgery
[portmanteau of `spam' or `spew' and `forgery'. Massive floods of
forged articles intended to disrupt a newsgroup. Typically these have
reasonable-looking headers but complete gibberish for content, making
the legitimate articles too difficult to find. This tactic has been
most notoriously used by the Church of Scientology to disrupt
discussion on the newsgroup alt.religion.scientology, but is
unfortunately not by any means confined to that group.
