No, your account cannot be private. Remember that engagement will come from unsubscribed users. As such, they need to be able to view your account to engage with it.
Because of the importance of public accounts, our system will check to confirm that your account is public before you place the order. If it is private, the order will not go through. Later on, if you put your account on private, the service stops automatically.
If you have a private account, you could theoretically turn it to the public whenever you make a post before putting it back to private. However, we do not suggest this as it may interfere with the proper running of our algorithms.
