AFAIK, moderated groups work basically by your news server literally e-
mailing the post to DIG's "Darwin" moderation host. The group gets a
lot quieter if this fails at Google Groups (which might happen
separately from normal newsgroup operation), but if it's everywhere,
either something under DIG's control has gone wrong, or the e-mail
service that delivers to him, or, perhaps, the propagated record that
identified t.o as a moderated newsgroup with DIG as moderator.
That's to say, it could be that the Feds are on to us. For
criticising the conduct of kooky legislators, and school boards, and
for praising them activist judges.
