Elon Musk said Twitter's lawyers told him he broke his nondisclosure agreement after tweeting about his plans to review fake accounts on the social media platform.

Tesla's CEO is in a $44 billion deal to acquire Twitter, though he said Friday it was "on hold" pending that account review. He took to his Twitter feed on Saturday evening to say his team would run a random sample of 100 accounts to assess the number of spam accounts, adding that the 100 is the same number Twitter uses to count spam and bots.

That is apparently what caught the lawyers' eyes. "Twitter legal just called to complain that I violated their NDA by revealing the bot check sample size is 100!," Musk tweeted on a thread. "This actually happened."

Musk has previously said that eliminating bots, spam and fake accounts could be the key to making Twitter a more valuable company. But Twitter shares have fallen in recent days since his plan to buy it and take it private was announced. Some suspected on Friday that his tweet that the deal was temporarily on hold revealed another motive: He wants to negotiate a better price.

Twitter (ticker: TWTR) stock fell 9.7% on Friday, to $40.72. Musk's current offer is for $54.20 a share.

The social media company has said bots make up 5% of users.

In the early hours of Sunday morning, Musk tweeted that the number is potentially far higher, possibly even more than 90% of daily active users.

Musk wasn't done yet, however. He told followers how to fix their feeds, warning that people are being manipulated by the algorithm that controls what people see in their feeds.

"I'm not suggesting malice in the algorithm," Musk said in a follow up tweet, "but rather that it's trying to guess what you might want to read and, in doing so, inadvertently manipulate/amplify your viewpoints without you realizing this is happening.
