Instagram comments are added under your posts, photos and videos. Random English comments will be provided by default if you do not provide any comments yourself, you only provide the link of your post. However if you would like to add your own custom comments, this is also possible by providing them inside the tex area when you make the purchase. Custom comments would be more realistic, as they would be content specific. Random comments are just randomly created texts and they may not always be relevant to your post.
