Twitter executives say the social media platform removes more than a million spam accounts every day. The figures were provided during a briefing on Thursday after Elon Musk threatened to stop the deal to buy Twitter.

In a conference call, the company reiterated its previous position that spam accounts make up significantly less than 5% of the users who receive advertising. The company stated further that human reviewers manually examine thousands of Twitter accounts randomly.

The company use a combination of public and private data to calculate the proportion of spam and bot accounts on the service and report it to shareholders. The company stressed that it did not believe that such accounts could be calculated externally because it needed private information.

“Twitter has and will continue to cooperatively share information with Mr. Musk to consummate the transaction in accordance with the terms of the merger agreement. We believe this agreement is in the best interest of all shareholders. We intend to close the transaction and enforce the merger agreement at the agreed price and terms,” a company spokesperson said in a statement.
