Official Pages of Tesla and SpaceX removed

New Delhi, Mar 24: Verified Facebook pages of Elon Musk's rocket company SpaceX and electric carmaker Tesla have disappeared, minutes after the Silicon Valley billionaire promised on Twitter to take down the pages when challenged by users.

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

Facebook pages of SpaceX and Tesla, which had millions of followers, are no longer accessible.

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