Accept ipv6 addresses as moderator.

"http_authentication_method=None" will bypass
HTTP AUTH and take the IP address as user
name, but the "moderator" column in each
database is limited to 20 chars, whereas
IPv6 addresses may be as long as 39 chars.
IPv6 was clearly not a consideration for
development.
