We’re taking a number of steps to limit this kind of unwelcome behavior. Accounts we identify using these services will receive an in-app message alerting them that we have removed the inauthentic likes, follows and comments given by their account to others. We will also ask them to secure their account by changing their password. People who use these types of apps share their username and password, and their accounts are sometimes used by third-party apps for inauthentic likes, follows and comments. Not only does this introduce bad behavior into the Instagram community, it also makes these accounts less secure.
We also know some people may have unknowingly shared their login credentials with a third-party app. If you receive an in-app message, simply change your password to revoke their access to your account. These new measures will be ongoing, and accounts that continue to use third-party apps to grow their audience may see their Instagram experience impacted.
Since the early days of Instagram, we have auto-detected and removed fake accounts to protect our community. Today’s update is just another step in keeping Instagram a vibrant community where people connect and share in authentic ways. We’ll have more updates in the coming weeks on additional measures we’re taking to tackle inauthentic activity on Instagram.
