Segal said the efforts to improve accounts along with other factors had a negative hit to monthly active users of 3 million in the quarter, which compares with the 1 million net decline, but added that efforts to improve quality of the accounts would take an even bigger bite out of third-quarter monthly users.
The user outlook came as Twitter reported higher-than-expected revenue thanks to the FIFA World Cup driving ad demand, strength in video ads and booming global ad revenue. Twitter's share price dropped almost 20 percent after the earnings report, matching a similar decline in Facebook's stock after its earnings report showed challenges ahead, partly a result of confronting toxic elements, too. Stalled American user growth and tighter rules on data protection in Europe may dampen revenue growth in two of the company's biggest markets.

Yet the market had more than doubled Twitter's value over the past year to $32 billion, and the valuation to 50 times estimated earnings.

In the meantime, Twitter's business, heavily dependent on advertising, is hanging in there.
