Elon Musk delivered a second letter of deal termination to Twitter Inc

following the world's richest man's subpoena of a whistleblower seeking details

on how the social media platform checks spam accounts

The firm deceived Elon Musk and authorities about the actual number of spam

bot accounts on the microblogging platform when it made a $44 billion offer for Twitter in July.

Musk sent a letter in July claiming that the company’s inability to prove

how many bots and spam accounts were on its service was a reason to back out of the deal.

According to Twitter’s response, his attempt to pull out of the agreement is “invalid and unjust”. 

According to a court document filed on Monday,

Mr. Musk has asked former Twitter security chief and whistleblower Peiter Zatko

information mostly regarding how the microblogging network measures spam accounts.
