is often done with cross-posting (e.g. any message which is crossposted to alt.rush-limbaugh and alt.politics.homosexuality will almost inevitably spam both groups). 3. To send many identical or nearly-identical messages separately to a large number of Usenet newsgroups. This is one sure way to infuriate nearly everyone on the Net.
