The forger could have chosen a much larger article number or a much
smaller article number, and there would have been no resulting risk of
bona fide articles from watdcsu failing to propagate because of it.
And such a forgery could probably go unnoticed.  Do any people or
software actually check for article numbers that are way out of
sequence?  I doubt it.

The sequence number for news articles has been updated on watdcsu so
that no innocent person will inadvertently post article 4000@watdcsu
and have it fail to propagate.  Article ID's 3979@watdcsu through
3999@watdcsu are available for anyone who wishes to forge them.
