Due to its nature (being an announcements newsgroup and not a discussion one), chile.grupos.anuncios is moderated - that is, there's a moderator that decides wether an article is acceptable or not for publishing. The current moderator is Miguel Farah, who's been in charge since the newsgroup was created.
chile.grupos.anuncios was created in 5/12/1994, as part of the reform to the newsgroup creation process within the chile.* hierarchy, after a suggestion made by Miguel Farah (in this Usenet posting).
