Emule is a P2P file transfer program, probably similar to what
bittorrent does.
The maker of the link is probably one of the seeder. anyone that
completed the download and leaves the emule client on will become a
seed, uploading the file to other peers.
However, because it is P2P, peers can also get bits of data from
other peers. so even if there are no seeds, if every peer has abit
of data that pieces up to 1 whole file, you should still be able to
get the files u wanted.
Correct me if I'm wrong
