badexpiry - find newsgroups with odd use of explicit expiry dates
badexpiry [ mincount minsize ]
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
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.
