Twitter limits bulk following to thwart spammers

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.

The total number of accounts that can be added to a user's list was cut to 400 from 1,000, the San Francisco-based internet firm said.

"Follow, unfollow, follow, unfollow. Who does that? Spammers," the Twitter safety team said in a tweet.

"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 policy bars use of the service for spreading spam, which it defines as "bulk or aggressive activity that attempts to manipulate or disrupt Twitter or the experience of users on Twitter to drive traffic or attention to unrelated accounts, products, services, or initiatives."
