How to See Who You Requested on Instagram
If you make your Instagram account private, you need to approve people before they can follow you on the social network or see your posts.
You'll generally get an Instagram follow request notification on your smart phone or other device with Instagram installed, and you can go through each Instagram friend request and approve or deny it. If you're using Instagram for a business, you may want to make your account public so that potential customers can see your posts and follow you without delay. You can make a separate account for personal posts or more sensitive ones, if you prefer.
Private and Public Instagram Accounts
By default, an Instagram account is public when you set it up. Anyone can follow you and see your photo posts and comments on others' posts and stories – other than direct messages you send to other users.
If you prefer, you can make your Instagram account private. In that case, your posts will only be visible to your followers, and you can control who follows you. When someone attempts to follow you, you will receive a notification and can allow or disallow them to follow you and see your posts and stories. If you do nothing, they will not be able to follow you or see your content.
Limitations of Privacy Settings
You can also block users from seeing or commenting on your posts, even if you keep your account public. This can be a good compromise if you don't want particular people seeing your posts, although they'll still be able to see them if they use, say, a friend's account or open your Instagram page in a private browsing tab. People don't get notified when you block them, but they may be able to figure out that they can no longer easily come across your profile and posts.
Note that if you set up your Instagram account to share your photos to other social media services, such as Facebook or Twitter, your privacy settings may be different there, and more people may be able to see your posts. Even if your account is private, it's possible that people who don't follow you could see your posts if someone you do follow shares them, either by taking a screenshot or physically showing someone using their own account.
Approving a Follow Request
If someone requests to follow you, you'll likely get a request on your phone. If you want to see all of your outstanding follow requests, tap the "heart" button to see all your notifications within the Instagram app.
Tap a request, and tap the "Confirm" button to accept the person as a follower or "Delete" to cancel the follow request on Instagram. If you delete the request, the person can request to follow you again unless you explicitly block them. If you delete a request by mistake, ask the requester to follow you again.
Requesting to Follow Someone
If you go to the Instagram profile page of someone whose page is private and who you do not follow, you can tap a button to request to follow that person. Tap it again to cancel that request if the person has not yet accepted.
If you want to see a list of everyone you have requested to follow, visit: http://instagram.com/accounts/access_tool/current_follow_requests in your Web browser. Log in to Instagram if you're prompted to do so.
Going Private or Public
If you want to make your Instagram account private so that people must request to follow you, tap the profile button, which looks like a silhouette of a person. Then, tap the menu button, represented by three horizontal lines in the top right corner of the app. Tap "Settings."
Tap "Account Privacy," and use the toggle switch next to "Private Account" to make your account private. Your existing followers will still be able to see your posts, unless you block them. Use the toggle switch again if you later want to make your account public.
