No, our service does not hurt your account; it will only boost it. To ensure this, we use real user accounts that our network has registered. Instagram has no way of knowing that you bought the service.
To take it a step further, we make your activity seem natural, so no one will notice that you bought our service. We send uneven amounts of likes, such as 51 to one post and 49 to another, if you have a package of 50.
