Twitter, like Facebook, has been under pressure from regulators in several countries to weed out hate speech, abusive content and misinformation, better protect user data and boost transparency on political ad spending.

The social media firm increased removals and suspensions of accounts in recent months, saying this was one reason the number of monthly users fell by 1 million to 335 million in the second quarter from the previous three months.

"Our second quarter results reflect the work we're doing to ensure more people get value from Twitter every day," said Jack Dorsey, Twitter's CEO. "We want people to feel safe freely expressing themselves and have launched new tools to address problem behaviors that distort and distract from the public conversation. We're also continuing to make it easier for people to find and follow breaking news and events, and have introduced machine learning algorithms that organize the conversation around events, beginning with the World Cup. These efforts contributed to healthy year-over-year daily active usage growth of 11 percent and demonstrate why we're investing in the long-term health of Twitter."

"We are pleased with our performance in the second quarter in DAU growth and delivering for advertisers," said Ned Segal, Twitter's CFO. "We're maintaining profitability while we make investments in the business, achieving strong revenue growth and introducing product updates that make Twitter both healthier and easier to use. Looking ahead, we remain optimistic about our ability to execute on our priorities and deliver value for advertisers and shareholders."

Facebook is still well ahead of Twitter in turning usage into money, generating $5.89 in revenue on average per user in the second quarter compared to $1.79 for Twitter.

Twitter has said increased video programming, including news shows and live sports, and investing in technology that automatically surfaces interesting content with limited user intervention should make the service appealing to first-timers.

Twitter said it lost some users due to the introduction of the General Data Protection Regulation in Europe in May but it did not note any revenue impact. Facebook has said it expects to take a moderate hit in coming quarters due to the new rules.

Twitter also saw usage fall after saying it would not subsidize users who accessed its application through text messages without paying messaging fees to wireless carriers.
