Hi, on Instagram, just like on Facebook, feed posts live and die according to a rather complicated pattern. For example, if a person stops liking you, the social network thinks that he is no longer interested in you, and stops showing him your posts or does it less often. The subscriber, in turn, perhaps unwittingly, stops receiving your content. Thus, you can quickly find yourself in the tail of the news feed and lose quality followers. You can buy instagram accounts, which are already very popular, but you should definitely constantly monitor and upgrade your account.
