A young man from Florida reportedly rejected an offer from Elon Musk to delete his Twitter account in exchange for US$5,000 (NZ$7500).
At 19 years old, Jack Sweeney has amassed more than 291,000 followers on his Twitter account ElonJet, which uses a computerised bot to gather information about Musk's private jet and automatically tweet flight details.
In November, the account gained the Tesla and SpaceX CEO's attention and Sweeney was contacted directly by Musk through Twitter.
Musk's first message was received on November 30 and said "Can you take this down?," reported Protocol. "It's a security risk."
