One could use Bitmessage for leaks - just create a channel and let people publish data to it.

Came here to say this. You could just publish to the general chan. However, bitmessage is no good for distributing data. It would be good for distributing how to get that data (torrent magnet, mega.nz link, encryption key, etc).
