Since anyone can edit anonymously and the date of the edit is so recent (within a day of the pastebins going viral), there is no reason to believe this etherpad document is authentic.

 There has been limited speculation about who the leaker(s) was. It has been [suggested](https://archive.is/sR8oa#selection-6009.1-6009.120) by some that it could be [Appelbaum](https://archive.is/pJOR4) due to his [insistence on publishing through **WikiLeaks**](https://archive.is/4FMxm#selection-5437.0-5437.110) and [his accepted offer](https://archive.is/4FMxm#selection-5857.0-5941.32) to [log the chat](https://archive.is/4FMxm#selection-6421.0-6421.50) for the Tor-internal mailing thread. Since the leaker took steps to conceal the origin of the transcript, it could just as easily have come from anyone participating in the channel, including Chasteen, who repeatedly says that [the story will be leaked](https://archive.is/4FMxm#selection-3913.0-3913.80). [Joseph Cox](https://archive.is/1dHZk) of [**Motherboard**](https://archive.is/6Bgjw) [claims](https://archive.is/5IQzy) they "[confirmed the legitimacy of the transcript](https://archive.is/NHubE#selection-1495.2-1495.61)" but did not specify how that was done. York, who was [called](https://archive.is/Bmgc3) "[highly promiscuous](https://archive.is/OIK0V#selection-215.8241-215.8384)" in the [first pastebin](https://archive.is/qVD57), believes that leaker [could be a woman](https://archive.is/Xf9rC#selection-3963.1-3963.93) and [someone](https://archive.is/N2rB6) else [fed her the information](https://archive.is/6D6xR#selection-6757.10-6757.90).
