How to block someone on Instagram
To block someone on Instagram, open their profile, tap the three dots in the top right corner, and select "Block." Instagram will then prevent that person from seeing your posts, stories, and account — they cannot find you through search, visit your profile, or message you. The block takes effect when ready, though Instagram does not notify them that you blocked them. They may figure it out if they try to visit your profile and see an error message, but they won't receive a notification from the app itself.
You can block someone whether they follow you or not. You can also block them from a direct message thread by tapping their name at the top of the conversation, scrolling down, and selecting "Block." On a desktop browser, visit their profile, click the three dots, and choose "Block User" from the menu.
Key Takeaways
- Blocking someone on Instagram prevents them from seeing your posts, stories, profile, and messages — the block is when ready and does not send them a notification.
- You can block from someone's profile (three dots menu), from a direct message thread (tap their name), or from desktop by clicking the three-dot menu on their profile.
- A blocked person cannot search for you, see your old posts, or contact you, but they can create a new account to view your public content if your profile is not private.
- If you change your mind, you can unblock someone at any time through your blocked accounts list in Settings, and they will not be notified of the unblock.
- Blocking is different from muting — muting hides someone's posts and stories from your feed without preventing them from seeing your content.
Where to find your blocked accounts list
To see who you have blocked, go to your Instagram profile, tap the menu icon (three horizontal lines), and select "Settings and privacy." Tap "Blocking" to view the full list of accounts you have blocked. From this screen, you can unblock anyone by tapping "Unblock" next to their name.
This list is private — only you can see it. Instagram does not show blocked accounts to other people, and the blocked person cannot see that they are on your list. If you unblock someone, they will not receive a notification, and you will not see a record that you previously blocked them.
What a blocked person can and cannot do
When you block someone, they lose access to most of your content. They cannot see your posts, stories, reels, or live videos. They cannot find your profile through the search function, visit your profile directly, or see your follower or following lists. If they try to message you, the message will not go through, and any existing direct message thread with them will disappear from your inbox (though the messages themselves are not deleted — they remain on their end).
However, blocking does not hide your public content from someone determined to see it. If your profile is public and they create a new account, they can view your posts, stories, and other public information from that new account. If your profile is private, a new account they create will also be blocked from following you unless you approve the follow request. Blocking is a barrier, not a permanent wall — it stops casual viewing but not someone with technical knowledge or persistence.
Blocking versus muting: which one to use
Blocking and muting serve different purposes. Muting hides someone's posts and stories from your feed without them knowing, but they can still see your content, visit your profile, and message you. Blocking prevents them from seeing your content and contacting you at all. Use muting when you want to step back from someone's content without cutting off contact — for example, if a friend posts things you find annoying but you still want to stay connected. Use blocking when you want to stop someone from contacting you or viewing your account.
To mute someone, visit their profile, tap the three dots, and select "Mute." You can choose to mute their posts, their stories, or both. You can unmute them the same way at any time.
What happens to your direct messages when you block
When you block someone, any existing direct message thread with them disappears from your inbox on your phone or computer. The messages are not deleted — they still exist on the blocked person's end, and they can still read what you wrote. However, they cannot send you new messages. If they try to message you, they will see an error or their message will not deliver.
If you unblock someone later, the old direct message thread will reappear in your inbox, and you will be able to see the full conversation history. The blocked person will also be able to message you again. Neither of you will receive a notification about the unblock.
Blocking someone who is harassing you
If someone is harassing you through Instagram, blocking is your first step, but it may not be your only one. After you block them, report their account to Instagram by visiting their profile (if you can still access it from a different account or before blocking), tapping the three dots, and selecting "Report." You can report for harassment, hate speech, spam, or other violations. Instagram reviews reports and may remove the account if it violates their Community Guidelines.
If the harassment continues from new accounts or escalates to threats, save screenshots of the messages or posts as evidence. You can report this to Instagram again, and if the behavior involves threats of violence or other serious crimes, you can report it to local law enforcement. Instagram also has a safety center with resources for people experiencing harassment, bullying, or abuse.
Unblocking someone and what they see
To unblock someone, go to Settings and privacy, tap "Blocking," find the person's name, and tap "Unblock." Once you unblock them, they can see your profile, posts, and stories again. They can search for you, follow you (if your profile is public), and message you. Unblocking does not automatically re-follow them or restore any previous follow relationship — if they unfollowed you before you blocked them, they will still be unfollowed after you unblock them.
Instagram does not notify the unblocked person that you have unblocked them. They will only know if they try to visit your profile and find that they can now access it, or if they search for you and find your account. There is no record of the unblock on either of your accounts.
Frequently Asked Questions
Can someone tell if I blocked them?
Instagram does not send a notification when you block someone, but they may figure it out. If they try to visit your profile, they will see a message saying the user cannot be found or that the content is not available. They can also try searching for you — if they cannot find you in search results when they could before, they may suspect a block.
If I block someone, can they see my old posts?
No. Once you block someone, they cannot see any of your posts, including ones they liked or commented on before the block. Those old interactions remain in your account history, but the blocked person cannot view them. If you unblock them later, they will be able to see your posts again.
What is the difference between blocking and restricting?
Restricting is a softer option than blocking. When you restrict someone, they can still see your posts and stories, but their comments and messages are hidden from you — you can review them in a separate folder if you want. They cannot see when you are online or when you have read their messages. Use restricting when you want to limit someone's access without a full block.
Can I block someone without them knowing?
Yes. Instagram does not send a notification when you block someone. However, if they try to visit your profile or search for you, they may realize they have been blocked. If you want to avoid contact without them knowing, muting is a quieter option.
If I block someone, do my mutual friends know?
No. Your mutual friends cannot see that you have blocked someone. The block is private — only you know who you have blocked. Your mutual friends can still follow and interact with the blocked person unless they have also blocked them.
