In those cases where the network is managed but a basic error like
this has been made there is little that can be done to save the
organisation from its own people. There are plenty of web pages that
will generate a prefix for you based on the process described in the
RFC e.g. https://cd34.com/rfc4193/ along with lots of open sourced
code to do the same.

Also, as Jeroen noted [0] on 9 December, the SixXS ULA registry was
intended as a joke and we can assume that a good number of the
registrations in it were jokes, too.

I think the IETF will need a more convincing argument if it is to
register a /8 of IPv6 space to a speculative registry with an unproven
business model.
