Elon Musk's move to temporarily cap how many posts Twitter users can read on the social media site could undermine efforts by the company's new Chief Executive Linda Yaccarino to attract advertisers, marketing industry professionals have said.

Musk announced Saturday that Twitter would limit how many tweets per day various accounts can read, to discourage "extreme levels" of data scraping and system manipulation.

Users posted screenshots in reply, showing they were unable to see any tweets, including tweets on the pages of corporate advertisers, after hitting the limit.
