Hipcrime (Usenet) - HipCrime's Newsagent

HipCrime's Newsagent software is a free and open source Usenet control client. The program is written in Java and allows the user to auto-cancel any messages on Usenet based on author, subject, organization, message-ID, or path. It also allows the user to replace the body of any message with text of their choosing. The software also monitors any posts you choose and reposts them if they are removed. Additionally, it allows regular users to act as Usenet Administrators and create (or remove) entire newsgroups.

CA Inc. has classified this as denial of service software, as well as flooder software, a specific type of denial of service attack.
