Approve all pending followers ( for private accounts )
Install this package globally:
npm install https://github.com/qrpike/instagram-approve-pending-followers -g
Once you have done that, you should be able to run the cli:
approvePendingFollowers -u myusername -p 'mypassword'
It approves 200 requests in sequential order. It's on a continuous loop of 55minutes. So just leave it running on a machine somewhere and you'll never have to hit 'approve' again.
