The service also suspended 456,989 accounts over child sexual exploitation. That's a decrease of six percent from the prior six months, and 96 percent of the accounts were detected using technology tools. On the platform manipulation and spam reporting front, Twitter says the number of "proactive challenges" of accounts dropped by 17 percent from the first half of the year to 194 million. About 75 percent of these were removed automatically, and Twitter says the data indicates people are having "fewer spammy interactions" on its service.

During the period, Twitter received 6,904 requests for information on 11,112 accounts from authorities across the globe, around the same number of requests as in the prior six months. It produced information on 56 percent of requests. In the US, the information disclosure percentage was 73 percent, a significantly higher level. Twitter received 2,092 requests from US authorities (which comprised 40 percent of all requests), linked to 3,860 accounts.

Compared with the first half of the year, there were eight percent fewer requests to remove content, related to 27,283 accounts, but there was an 84 percent increase year-over-year. Almost three-quarters of the requests came from Russia and Turkey.
