The social network said Friday that it had 335 million monthly users around the world in the second quarter, down from 336 million users in the quarter prior. The number of monthly users could also decline by "mid-single-digit millions" in the third quarter, Twitter warned. The stock fell more than 15% in premarket trading Friday after the earnings results, before rebounding somewhat. It cracked down on fake accounts, purging suspicious accounts from users' follower metrics and removed 143,000 apps last quarter for violating its policies. Like Facebook, Twitter is working to comply with the General Data Protection Regulation, which took effect in Europe in the second quarter.
