In a fresh SEC filing this morning, Twitter shared a letter it received from Elon Musk's legal team indicating displeasure with the company's offered information regarding the level of "spam and fake accounts" on its service. This is the same concern that the technology entrepreneur has posted about extensively since his deal to buy the social media platform was settled earlier in the year.

Per the letter -- which you can read in its entirety here -- Musk considers Twitter's "latest offer to simply provide additional details regarding the company’s own testing methodologies, whether through written materials or verbal explanations, [as] tantamount to refusing [his] data requests," requests that the SpaceX and Tesla CEO says will help "facilitate his evaluation of spam and fake accounts on the company’s platform."

The letter says that more data (and not just explanation of how the existing data was gathered) on Twitter's non-human users -- both natural and spam -- is important for helping close the transaction from a financing perspective. "As Twitter’s prospective owner, Mr. Musk is clearly entitled to the requested data to enable him to prepare for transitioning Twitter’s business to his ownership and to facilitate his transaction financing," the letter reads.

At the end of the short correspondence, Musk's legal team threatens to kill the deal (emphasis: TechCrunch):

Fighting words indeed.
