Newsgroup names?

Sporgery resembles crapflooding, which is also intended to disrupt a forum. However, sporgery is not merely disruptive but also deceptive or libellous -- it involves falsifying objectionable posts so they appear to come from newsgroup regulars. The purpose is not merely to jam the forum, but also to blacken the reputations of its regular users by falsely signing their names to offensive posts.
