Owlead will automatically clean your account from the non-followers or from all following, depends on the settings configured in your campaigns.
Bear in mind that Owlead will only unfollow the accounts previously followed by the platform. It won’t attempt to unfollow accounts you’ve manually followed in the past.
The platform leaves a 2-day gap between a follow and an unfollow.
Important: the unfollowing process (aka Cleanup) runs for Active and Paused campaigns. So, if you pause a campaign it will keep cleaning based on your settings.
