debian-multimedia.org was an unofficial, popular repository of Debian
packages. After a discussion last year, the service moved to another domain.
Debian offered to cover costs for the transfer of the debian-multimedia.org
domain to prevent it from expiring and falling into a domain squatter's hands
(or worse). Unfortunately, the debian-multimedia.org maintainer decided not
to cooperate with Debian, and let the domain expire. The domain has now
apparently been registered again by someone unknown to Debian (TTBOMK).
This is a good example of the importance of the use of cryptography to secure
APT repositories (and of the importance of not blindly adding keys).
