Online platform X could introduce a monthly fee for all users, its owner Elon Musk said Monday, citing the need to cut down on bots.

The tech tycoon has made multiple changes since buying the site for $44 billion in October last year, when it was known as Twitter.

He has fired thousands of employees, introduced a paid premium option, cut content moderation and reinstated formerly banned accounts including that of former U.S. president Donald Trump.
