As shown in the picture below, This user is a private account. If you are not his follower, You cannot see his posts or follower list.
I’m sorry for IGExporter can’t do that, because we scrape all datas without Instagram account (100% safe for you)
Fortunately, We find a great extension to help you to get followers from a private account.Let me show how this extension works.
