Huhu is a web application to moderate Usenet groups.

Basic workflow

  1. Emails are sent to the submission address
  2. Retrieved mails are stored in database
  3. The web application visualizes the stored mails
  4. Human moderators use the web application to classify mail:
    • Approved submissions are sent to the news server
    • For rejected submissions a rejection notice is sent to the author via mail
    • Submissions can also be silently ignored
    • Mails classified as spam are silently ignored but also train the spamfilter
