NAME

       badexpiry - find newsgroups with odd use of explicit expiry dates

SYNOPSIS

       badexpiry [ mincount minsize ]

DESCRIPTION

       Badexpiry  reports  (on  standard  output)  newsgroups  with suspicious
       patterns of use of explicit expiry dates in articles.  Specifically, it
       reports groups with more than mincount (default 15) articles, more than
       90% of all articles, or more than minsize (default 500) KB of  articles
       having  explicit  expiry  dates  more  than 10 days after their arrival
       dates.

       Such reports are not  necessarily  indicative  of  abuses—for  example,
       news.announce.newusers  legitimately has most or all of its articles on
       long expiry—but investigation may be in order.
