Simple moderation of a newsgroup on Usenet approximated running a mail list: known users (like list subscribers) could post anything to the newsgroup, while messages from unknown users would be diverted into something like a mail spool, and, if approved by a moderator, would be posted to the newsgroup. A moderator could add or remove users (email addresses) from the known users list. Complaints about known user posting behavior could be directed to a moderator, who might or might not take action. Multiple moderators are possible, see the "STUMP" software mentioned in the Reg article. Attempts to "retro-moderate" previously posted messages by using the NNTP cancel mechanism were only widely effective in the very early 1980s, and rapidly became problematic due to disagreements, forgery, and vandalism. source: Hosted a moderated newsgroups FAQ for decades, helped convert news.newusers.questions to a moderated group - which may have been a case of "we had to destroy the village to save it" :-(
