Bots are allowed on Twitter, though under the company’s policy, such accounts are supposed to indicate that they’re automated. The platform has even launched a label for “good” bots, such as @tinycarebot, an account that tweets self-care reminders. Spam bots, however, are not permitted, and the company has policies meant to combat them. Users are encouraged to report policy violations. The company locks accounts with suspicious activity. To get back in, users may have to provide additional information such as a phone number or solve a reCAPTCHA challenge, which entails completing a puzzle or typing in a phrase seen in an image to confirm they’re human. Twitter also can permanently suspend spam accounts. The company estimated that fake accounts and spam accounted for less than 5% of its daily active users in the fourth quarter of 2021.
