Tesla chief Elon Musk on Friday said that his plan to buy Twitter for $44 billion is currently on hold temporarily citing pending details on spam and fake accounts on the platform.

Soon after Musk’s tweet, several people took to the micro-blogging site to express their confusion over the now ‘hanging in the air’ Twitter deal. After Musk’s tweet, stock in both Twitter and Tesla swung sharply in opposite directions, with Twitter’s stock tumbling 18%.

Some users on the micro-blogging site accused the 50-year-old of stock market manipulation.

“I feel like Elon Musk should finally be charged with stock market manipulation,” Musk tweeted.

While another person said that most things done by Musk comes from what Fitzgerald called “the vast carelessness” of the truly wealthy.

Several users also joked about Musk’s flaky mood.
