What blocking does and doesn't do
When you block someone on Instagram, that person can no longer see your profile, posts, stories, or follower list. They cannot send you direct messages, and any existing conversation between you disappears from your inbox (though they can still see it on their end). If they search for your username, your profile will not appear in results for them.
Blocking is not the same as muting. A muted account still follows you and can see your posts if they visit your profile directly — you just won't see their posts or stories in your feed. Blocking is the stronger action: it severs the connection entirely and prevents them from finding you through search.
One important limit: blocking does not prevent someone from viewing your profile through a different account, a web browser while logged out, or by asking a friend to check your posts. If someone is determined to monitor you, blocking one account is a starting point, not a complete barrier.
Key Takeaways
- Open the person's profile, tap the three dots in the top right, and select "Block" from the menu.
- A blocked person cannot see your posts, stories, or profile, and any direct messages between you will vanish from your inbox.
- You can unblock someone at any time by finding them through a search, tapping the three dots, and selecting "Unblock".
- Blocking is not private — the person may notice they can no longer find your profile or that a conversation has disappeared.
How to block someone from their profile
The fastest way to block someone is to visit their profile directly. Open Instagram, search for the person's username or find them through your followers or following list, and tap their profile name to open it.
Once you are on their profile, look for the three horizontal dots (called a menu icon) in the top right corner of the screen. Tap it. A menu will appear with several options. Scroll down until you see "Block" and tap it. Instagram will ask you to confirm — tap "Block" again in the confirmation window.
After you block them, their profile will no longer be visible to you in search results or your followers list. If you navigate back to where you found them, they will be gone.
How to block someone from a direct message
If someone is messaging you and you want to block them without visiting their profile, you can block them directly from the conversation. Open your direct messages, find the conversation with the person you want to block, and swipe left on it (on iPhone) or long-press it (on Android).
A menu will appear with options including "Block". Tap it and confirm. The conversation will disappear from your inbox when ready, and that person will no longer be able to message you.
Alternatively, open the conversation, tap the person's name at the top of the chat, and look for a "Block" option in their profile details. The exact location varies slightly depending on whether you are using iPhone or Android, but the option is always present in the conversation header.
What happens after you block someone
Once the block is in place, the other person will notice changes on their end. They will no longer see your profile when they search for you. If they try to visit your profile directly through an old link or bookmark, they will see a message saying the user could not be found or that the profile is not available.
Any direct message conversation between you will disappear from your inbox, but they will still see the conversation thread on their side — they just cannot send new messages to you. If they try to message you, their message will not go through, and they may see an error or a message saying you are not accepting messages from them.
They will not receive a notification that says "you have been blocked." However, if they were following you, they will notice they are no longer following you. If they search for your username and cannot find you, they may reasonably conclude they have been blocked.
How to unblock someone
If you change your mind, you can unblock someone at any time. Search for their username in the Instagram search bar. If they are blocked, you will see a message on their profile saying "User Not Found" or "No Posts Yet" with a note that the account may not exist or may have been removed.
Tap the three dots in the top right corner of that profile. Select "Unblock" from the menu. Confirm the action. The person will when ready be unblocked, and they will be able to see your profile and posts again.
Unblocking does not automatically re-follow them or restore old direct messages. If you want them to follow you again, they will need to send a follow request or you will need to follow them back manually.
Blocking on Instagram versus other platforms
Instagram's blocking feature works similarly to blocking on Facebook (which Instagram owns), but with some differences. On Facebook, a blocked person cannot see your profile, posts, or past comments on mutual friends' posts. On Instagram, the blocking is cleaner because there is less shared history — blocked users straightforward cannot find you.
On Twitter (now called X), blocking prevents someone from following you and removes them from your followers, but they can still see your public posts if they log out or use another account. Instagram's blocking is more complete: a blocked person cannot see your posts at all unless they use a different account.
If you are blocking someone who harasses you across multiple platforms, block them on each one separately. There is no single block that covers Instagram, Facebook, and other apps at once.
When blocking is not enough
If someone is creating fake accounts to contact you after you block them, or if they are harassing you in other ways, blocking alone will not solve the problem. Report the account to Instagram by tapping the three dots on their profile and selecting "Report User". Choose the reason that best describes the behavior — harassment, spam, or hate speech are common options.
Instagram's support team reviews reports and may remove the account or restrict the person's ability to message you. If the harassment is severe or involves threats, you can also report it to local law enforcement and provide them with screenshots of the messages.
For ongoing harassment, consider making your account private so that only people you approve can follow you and see your posts. You can change this in your account settings under "Privacy".
Frequently Asked Questions
Will the person know I blocked them?
Instagram does not send a notification that says "you have been blocked." However, if they search for you and cannot find your profile, or if they notice they are no longer following you, they may figure it out. There is no way to block someone secretly.
Can I block someone without them seeing that I unfollowed them?
When you block someone, they are automatically unfollowed. If they check your profile before you block them, they will see that you are no longer following them. Blocking happens when ready, so there is no way to unfollow first and then block separately to hide the action.
What if I block someone and then unblock them later?
Unblocking restores their ability to see your profile and posts, but it does not restore old direct messages or automatically re-follow them. They will need to follow you again if they want to see your stories in their feed.
Can I block someone temporarily?
There is no temporary block feature on Instagram. You can unblock someone at any time, but while they are blocked, the block is complete. If you want to hide someone's posts without blocking them entirely, use the mute feature instead — search for their profile, tap the three dots, and select "Mute".
Does blocking someone delete our past conversations?
Blocking deletes the conversation from your inbox, but the other person can still see it on their end. They cannot send new messages, but they can scroll back through old messages you sent before the block. If you want to delete messages permanently, you will need to unsend them individually before blocking.
