Protesters carrying an inflatable angry emoji greeted Facebook Inc. shareholders as they gathered for the company's annual meeting on Thursday, the latest sign of its struggle to shake off privacy scandals and rein in fake news and hate speech.

The social media giant again faced demands for reform at Thursday's meeting, including shareholder proposals that called for revamping the company's voting structure and ousting Chief Executive Officer Mark Zuckerberg as chairman.

The measures had little chance of succeeding, as a dual class share structure gives Zuckerberg and other insiders control of about 58 percent of the votes. Many investors have shrugged off the scandals swirling around the company, as it has beaten Wall Street's estimates for revenue growth and continues to add users globally.
