Twitter on Monday trimmed the number of accounts that a user can follow in a single day in an effort to fight spam at the micro-blogging platform.
Follow, unfollow, follow, unfollow. Who does that? Spammers. So we’re changing the number of accounts you can follow each day from 1,000 to 400. Don’t worry, you’ll be just fine.— Twitter Safety (@TwitterSafety) April 8, 2019
