Twitter Inc on Tuesday posted better-than-expected quarterly revenue and a surprise increase in monthly active users, showing its efforts to police spam accounts and abusive posts were helping lure more users and advertising dollars.

Axar.az reports citing foreign media that Twitter shares surged more than 8 percent in premarket trade.

Like Facebook Inc. Twitter has been under pressure from lawmakers over privacy concerns and political influence activity on its service. Twitter’s clean-up has included removing thousands of spam and suspicious accounts, which it had blamed for sequential declines in monthly users in recent quarters.

Advertisers have welcomed those moves, but the company still faces a broader backlash against social media.

U.S. President Donald Trump, a frequent tweeter with one of the most-followed accounts, on Tuesday called for the creation of “more, and fairer” social media companies in response to discrimination he said he has faced as a Republican from Twitter, without presenting evidence.

“We enforce the Twitter Rules dispassionately and equally for all users, regardless of their background or political affiliation,” a Twitter representative said. “We are constantly working to improve our systems and will continue to be transparent in our efforts.”

It was the company’s last quarter of disclosing its monthly active user (MAU) count, and Twitter from now on will only provide its “monetizable” daily active users, created to measure people exposed to advertising on a daily basis.

Analysts were encouraged by signs Twitter had turned a corner in terms of monthly user growth and better appealing to advertisers, but said that the new user metric could make comparisons between Twitter and social media rivals more difficult.
