In an effort to prevent spammers from taking control over Twitter, the social media application is limiting the number of followers that can be included in an account on a single day. Previously that number was 1,000 and a tweet from the twitter safety account uncovers that the new cap is 400. This is supposed to stop spammers from including a large number of followers and then erasing them in a “bulk, forceful or unpredictable manner” that violates Twitter’s rules.
By including all these followers, spammers hope that the majority will follow them back. Those that do will soon find a various number of spams in their timeline. Those that don’t will before be unfollowed by the spammers. This is a cycle that proceeds over and over again. In a series of tweets, Twitter’s Yoel Roth clarifies that lowering the number of followers a day from 1,000 to 400 won’t prevent the spammers, but it will slow them down. The 400 limits will “make each spam account less viable, slower, and more costly to operate.”
Roth adds that Twitter chooses to make the new cap 400 because it enables people to follow the accounts they’re keenly on while it stops the most spam. Almost 50% of the accounts that were following 400 Twitter users each day were engaged in churning, which is defined as “repeatedly following and unfollowing the same accounts” trying to develop the growth of the number of followers that a Twitter subscriber has. He includes that 99.87% of Twitter users will be unaffected by this new rule.
