In december 2007, well-known Shareaza.com was hijacked by Discordia Ltd using pressure to the original domain owner to release it. Now it happened again with the Lphant project, an edonkey and bittorrent client. Discordia Ltd has replaced the client on the original website with its own fake version.[1] The latest original version is available under savelphant.wordpress.com.
You can find more information about the fight against Discordia in the official Shareaza Forum at pantheraproject.net[2].
