SpaceX Facebook page disappears after Elon Musk promises on Twitter

March 23 (Reuters) - Rocket company SpaceX's verified Facebook page disappeared on Friday, minutes after its founder and Silicon Valley billionaire Elon Musk promised on Twitter to take down the page when challenged by a user.

"Delete SpaceX page on Facebook if you're the man?" a user tweeted to Tesla Inc chief Musk. His response: "I didn’t realize there was one. Will do."

SpaceX's Facebook page, which had more than 2.7 million followers, is no longer accessible.

Musk had begun the exchange by responding to a tweet from WhatsApp co-founder Brian Acton of the #deletefacebook tag.

"What's Facebook?" Musk tweeted.
