Until at least March 2005, Facebook officially endorsed the p2p client, saying on their site "Wirehog is a social application that lets friends exchange files of any type with each other over the web. Facebook and Wirehog are integrated so that Wirehog knows who your friends are in order to make sure that only people in your network can see your files. Facebook certifies that it is okay to enter your facebook email address and password into Wirehog for the purposes of this integration."
