Twitter introduced measures to evaluate account metrics in near-real time.

The platform is able to recognize bots activity detecting synchronized operations conducted by multiple accounts.

Twitter announced it will remove follower and engagement counts from accounts flagged as suspicious that have been put into a read-only state until they pass a challenge, such as confirming a phone number.

“So, if we put an account into a read-only state (where the account can’t engage with others or Tweet) because our systems have detected it behaving suspiciously, we now remove it from follower figures and engagement counts until it passes a challenge, like confirming a phone number.” reads the blog post published by Twitter.

“We also display a warning on read-only accounts and prevent new accounts from following them to help prevent inadvertent exposure to potentially malicious content,”
