Valid fear, my friends.
Instagram has been cracking down on apps that use their platform in any way other than how it was meant to be used. Recently, an app called Instagress which is a bot software that comments on posts using your Instagram account was literally shut down. Instagress's official announcement said they were asked by Instagram but we have a feeling they were told by Instagram, through lawyers. Yikes! So it's natural to feel a bit weary when using an app in your Instagram strategy that might give you an edge on other users.
