Usenet newsgroups have been under a series of attacks recently. Among many
other things, vandals have been flooding the control.newgroup group with
bogus newgroup messages setting moderated groups unmoderated. If the group
has been marked moderated and it doesn't show as moderated any more, or if
you had been getting a 'this message has been mailed to the moderator'
message and you don't anymore, this is probably what happened. Contact me
at atxfa-contact@burchard.org. Also, contact support at your ISP and
suggest that they turn off auto-newgrouping -- that all newgroups should
be either checked against their PGP key and a trusted newgrouper list, or
sent to the news-admin for action.
