Elon Musk, CEO of Tesla and SpaceX, has called on the U.S. Securities and Exchange Commission to look into the social network’s user numbers. The SEC has been aware of Twitter’s murky metrics for years. Musk agreed to buy Twitter last month for $44 billion, but has since said the deal is on pause as he looks into bots, spam and fakes. Twitter has said it still expects the transaction to go through at the agreed upon price of $54.20 a share. Twitter’s stock has given up all its gains since Musk first disclosed his 9% stake in the company early last month. The company said it estimated the average of false or spam accounts represented fewer than 5% of mDAUs during that period. . . .
