What blocking does on Instagram
When you block someone on Instagram, that person can no longer see your profile, posts, stories, or reels. They cannot find you by searching your username, cannot message you, and cannot see your follower or following lists. If they try to visit your profile directly, they will see a message saying the user is not found or that the account is not available.
Blocking is not the same as muting. If you mute someone, they can still see your posts and stories — you just won't see their activity in your feed or their stories in your story queue. Blocking is the stronger option when you want someone to have no access to your content at all.
Instagram does not notify the blocked person that you blocked them, but they may figure it out if they try to visit your profile or search for you and cannot find you. If they unblock themselves by creating a new account or asking a friend to check, they will see that your profile is no longer visible to them.
Key Takeaways
- You can block someone from their profile, from a comment they made on your post, or from a direct message conversation.
- A blocked person cannot see your profile, posts, stories, or reels, and cannot message you or find you by searching.
- Blocking someone does not delete past messages or comments they made before the block — those remain visible to you unless you delete them yourself.
- You can unblock someone at any time by going to your blocked accounts list in settings, and they will regain access to your profile.
How to block someone from their profile
Open Instagram and navigate to the person's profile. You can search for them by username or find them through your followers, following list, or direct messages. Once you are on their profile, tap the three dots in the top right corner of their profile header (on mobile) or look for the menu icon.
A menu will appear with several options. Select "Block" from the list. Instagram will ask you to confirm — tap "Block" again. The person is now blocked, and their profile will disappear from your view.
On a computer, the process is the same: go to the person's profile, click the three dots or menu icon, and select "Block" from the dropdown menu.
How to block someone from a comment or direct message
If someone has left a comment on your post that you want to block them for, tap on the comment. A menu will appear with options including "Block." Tap it, and confirm the block. You can also delete the comment at the same time if you want.
If you are in a direct message conversation with someone and want to block them, open the conversation. On mobile, swipe left on their name (iPhone) or long-press their name (Android), then select "Block." On a computer, click the three dots next to their name in the conversation and select "Block."
What happens to past messages and comments after you block
Blocking someone does not automatically delete messages you have already exchanged with them. The conversation will remain in your direct message inbox, and you can still read what was said. However, the blocked person cannot send you new messages, and they cannot see that the conversation exists on their end.
Comments the blocked person made on your posts before the block will still be visible on your profile. If you want to remove them, you will need to delete them yourself by tapping the three dots on the comment and selecting "Delete." Blocking alone does not erase their past activity on your account.
How to unblock someone
If you change your mind and want to unblock someone, go to your profile and tap the menu icon (three horizontal lines). Select "Settings and privacy," then "Blocking." You will see a list of all the accounts you have blocked.
Find the person you want to unblock and tap "Unblock" next to their name. Confirm the action. Once unblocked, they can see your profile and posts again, and they can message you and search for you by username. They will not be notified that you unblocked them.
On a computer, go to Settings and privacy, then Blocking, and follow the same steps.
When blocking is not enough
If someone is harassing you repeatedly, creating fake accounts to contact you after being blocked, or posting threatening content, blocking alone may not solve the problem. Instagram has a "Report" option on every profile and post. Tap the three dots and select "Report," then choose the reason — harassment, hate speech, or threats are all options Instagram takes seriously.
You can also restrict someone instead of blocking them. Restricting is less visible to the other person — they can still see your public posts, but their comments on your posts will only be visible to them, and you won't see their direct messages unless you choose to look at them. This is useful if you want to limit someone's access without making it obvious that you have done so.
If the harassment continues or involves threats, you can contact Instagram directly through the app or report the account to local law enforcement if the behavior is illegal in your area.
Blocking on Instagram versus other platforms
Instagram's blocking feature works similarly to blocking on Facebook (which is owned by the same parent company, Meta), but differently from Twitter, TikTok, or Snapchat. On Twitter, a blocked person can still see your public posts if they log out or use a different account. On TikTok, blocking prevents someone from finding your profile and messaging you, but they can still see your public videos if they search for you on a browser. On Snapchat, blocking prevents all contact and visibility.
If you use multiple social media platforms and want to block someone across all of them, you will need to block them on each platform separately — there is no single block that applies everywhere. Keep track of where you have blocked someone so you remember which platforms they can still access.
Frequently Asked Questions
Can someone tell if I blocked them on Instagram?
Instagram does not send a notification when you block someone, but they may figure it out by trying to visit your profile or search for you and finding that you are not visible. If they ask a friend to check your profile, the friend will be able to see it. There is no way to block someone completely invisibly.
If I block someone, will they see my old posts or comments I made on their profile?
No. Once you block someone, they cannot see any of your posts, comments, or likes. Old comments you made on their posts will still be visible to them, but they cannot see your profile to find those comments. If you want to remove a comment you made on their post before blocking, you will need to delete it yourself first.
What is the difference between blocking and restricting?
Blocking removes all access — the person cannot see your profile, posts, or stories. Restricting is less visible: they can still see your public posts, but their comments on your posts will only be visible to them, and their direct messages go to a separate folder you can ignore. Restricting is useful if you want to limit someone's access without making it obvious.
Can I block someone who has already blocked me?
If someone has blocked you, you cannot see their profile to block them back. However, you can still block them by searching their username directly in the search bar. Even though you cannot see their profile, the block will go through. This prevents them from unblocking you and contacting you later.
Will blocking someone remove them from my followers or following list?
Yes. If you block someone who follows you, they will be removed from your followers list. If you follow them, they will be removed from your following list. The block takes effect when ready, and the person will no longer appear in either list.
