I know this is a long-shot, but does anybody know how I can reach the #Usenet admins at #GigaNews? A user at GigaNews generated a huge flood of spam postings to moderated newsgroups this morning, and as the maintainer of two of the relay mail servers for moderated newsgroups, I need to contact the admins at GigaNews to make sure they know about it and are taking steps to prevent it from happening again.
for reach if you've got any Usenet folks in your network, please.
