On the Vault:
1) there is a contact option for anonymous users under the About->Who->Contact menu.
(I buried it that far to reduce the spam-flood, which is also the reason for the IP blocking).
2) Nwvault irc channel is active and quick, when the right people are on.
3) There are several other forums mentioned above. Word does get around.
4) you can email webmaster@
neverwintervault.org (so you always have that option in a pinch, even if I am old-man slow sometimes.
As far as IP blocking being nonsense...
Project Q which does not have that feature currently has 22,000 accounts... all but 50 or so of them are spam accounts.
I am in the process (oh, joy!) of cleaning them out for Meaglyn as we type.
The lack of automated IP blocking contributed greatly to IGN shutting down the old Vault, as well. (If you recall, I was admin there before the fall :-P ).
But just like Captcha and other anti-spam measures, there will always be mistakes made by bots.
Hence the Fallout series...
