Unfortunately, your method allows you to add inactive users who will only change the number in your subscriber count. In addition, this can lead to blocking your account. Therefore, I would not use your method. One day I got very interested in this issue, and after a little searching on the internet, I found another method that adds free ig followers to any account. These followers will be real and boost activity on your account, which will encourage development. This method is much more useful and effective than the one you described.
