So far it is totally unclear to me who is supposed to do what in order to
make this issue disappear. It would appear that some of the work has to be
done by authorized personnel able to access the website server. The
question is what work is exactly needed from potential unauthorized helpers
before this can happen.
In particular since it is not clear what kind of operations in the course
of ssh into lilypond.org will or will not be refused. Short of an actually
useful task description, I see little chance that this issue can be tackled
or even approached successfully.
