If the person you are going to follow has a public account on Instagram, then you don’t have to click or give a ‘follow’ request on Instagram. You can follow them directly by clicking on follow button. On the other hand, if the person on Instagram has a private account, then you have to first give a ‘follow’ request to them. Instagram will send the notification message to their phone. Based on your notification, they might either accept your request or reject you. Most people on Instagram would like to keep their following list to a limited number, and they will follow only certain people on Instagram. On Instagram, people you follow will put stories on their page. The stories will appear on the top page of Instagram. Stories that are newly posted will be circled in red, and the stories which are viewed by you will not be circled.
