Restrict vs Block on Instagram: Which One to Use
Restrict quietly limits one account without telling them, and Block removes their likes, comments and ability to tag you, also without telling them, but neither scales to comment or DM volume.

Instagram Restrict: What It Actually Does
Restrict is a privacy control for one difficult account, applied without a confrontation. Instagram's Help Center says that once you restrict someone, their new comments on your posts are visible only to them until you approve, delete or ignore each one, and you stop getting notified of future comments from that person. They also cannot see when you are online or whether you have read their messages. Any chat with them moves out of your main inbox into Message Requests, where you can read what they send without them knowing you have seen it (Instagram Help Center, Restrict or unrestrict someone on Instagram).
Restrict is free, reversible from the same menu, and applies to a single account. It does not stop the person from viewing your posts if your account is public, and it does nothing about ten other accounts doing the same thing at once.
How to restrict someone
From the Instagram app, go to the person's profile by tapping their username from a Feed or story post, or by searching for them, then tap Options in the top right, then tap Restrict. The same menu has Unrestrict if you change your mind. Instagram's Help Center notes you can also restrict someone directly from a comment, and that you can restrict multiple people from your comments at once. For harassment from groups of accounts, the same page points to a separate tool, Limit, to temporarily hide those comments instead.
Instagram Block: What It Actually Does
Block is the stronger, more final version. Instagram's Help Center says the block does not notify them. Their existing likes and comments on your photos and videos are removed, and unblocking later does not bring them back. They can still see your likes and comments on posts shared by public profiles or profiles they follow (Instagram Help Center, What happens when you block someone on Instagram).
Block is also free and one account at a time. A blocked person is not notified either way, and nothing about either tool is built to handle more than one account at once.
How to block someone
Instagram's Help Center says you can block or unblock people from their profile or directly from a chat, and you can view your full blocked list from your settings. Instagram's Help Center page in fact gives you that option: when you block someone, you can choose to block just their current profile, or to block their profile along with other existing profiles they may have or profiles they may create.
Why Spam Under an Instagram Ad Looks Different
Instagram comments cannot contain clickable links, so the spam that shows up under a paid Instagram post is rarely a bare URL. It is discount codes, competitor handles, fake giveaway accounts and comments pushing people to check a bio link, all riding the attention the ad already paid for. None of that is the single-account harassment Restrict or Block was designed to stop. It is a volume problem spread across accounts, which is also why Facebook's version of the same ad can carry an outright scam link in the comment itself, a risk Instagram's comment format does not share.
Two Other Native Controls Worth Knowing
Before reaching for Restrict or Block on every comment, two broader Instagram settings are worth turning on first, since they work on content rather than one account at a time. Hide unwanted comments is on by default and automatically hides comments with common offensive words, phrases or emojis. Hidden Words lets you add your own list of words, phrases, numbers and emojis for Instagram to hide the same way (Instagram Help Center, Hide comments or message requests you do not want to see on Instagram). A comment hidden this way stays visible only to the account owner and the person who wrote it, and that person is not told.
Neither setting reads intent the way a human or an AI moderator would. They work from lists of words and patterns, so a spam comment built entirely from emoji, a brand-new slang term, or a discount code with no offensive language can slip through untouched, and a real customer who happens to use a flagged word can get hidden by mistake. They cut down the pile a team has to work through by hand. They do not replace judgment on what is left in it.
Restrict vs Block, Side by Side
Question | Restrict | Block |
|---|---|---|
Tells the other person | No | No |
Can they still see your public posts | Yes | Not stated by Instagram. Their old likes and comments on your posts are removed and they can no longer mention or tag you |
What happens to their comments | Visible only to them until you approve, delete or ignore | Removed from your posts, do not return if unblocked |
Effort to apply to many accounts | One account at a time | One account at a time |
When the Problem Is One Person
For a single account that is annoying but not dangerous, such as an ex who keeps commenting or a follower who will not drop a conversation, Restrict is the lighter option. It defuses the interaction without the other person necessarily realizing anything changed, and it stays reversible if the situation improves.
For harassment, impersonation or anyone you want fully disconnected from your account, Block is the right call. It is the only one of the two that removes someone's existing likes and comments and keeps them from mentioning or tagging you, and the Help Center is explicit that it carries no notification either.
Neither decision needs to be permanent. Restrict and Block both have an Unrestrict and Unblock option in the same menus, so testing the lighter option first and escalating to a full block later costs nothing but a few taps. The same applies in reverse: if you already blocked someone and later decide the situation has cooled off, Unblock sits in the same menus, though Instagram does not promise your old likes and comments come back once you do.
When the Problem Is Comment and DM Volume, Not One Person
Neither tool was built for a different kind of problem: a paid Instagram ad that pulls in scam links, fake giveaway accounts and competitor bait across comments from accounts that keep appearing. Restricting or blocking each one by hand does not scale, and new accounts keep arriving faster than one person can tap through profiles. This is the gap Exerta's comment moderation is built for: it reads Facebook, Instagram and TikTok ad comments and moderates and replies at the volume a paid campaign produces, instead of acting on one account at a time.
The Short Version
Restrict and Block are free, native, and good at what they are built for, which is managing one account's access to you. A brand running paid social and watching the same comment problem repeat across a growing number of accounts is looking at a different, bigger problem, and that is where a paid moderation layer like Exerta earns its place alongside the native tools, not instead of them.
FAQ
What is the difference between Restrict and Block on Instagram?
Restrict hides a person's new comments from everyone but them and moves their messages to Message Requests, without telling them. Block removes their existing likes and comments from your content and stops them from mentioning or tagging you, also without a notification.
Does Restrict notify the other person?
No. Instagram's Help Center does not list any notification sent to a restricted account. They simply stop seeing your online status and read receipts, and their new comments become visible only to them unless you approve them.
Does Block notify the other person?
No. Instagram's Help Center states plainly that a block does not notify the person, and it describes no other notification either.
Can I use Restrict or Block to handle spam on my ads?
You can, one account at a time, and new spam accounts will keep arriving faster than you can restrict or block them. Native tools such as Hidden Words and the blocked comment filter catch some of the volume, but neither Restrict nor Block was designed for ad-scale spam.
Is there a brand-scale alternative to Restrict and Block?
Yes. Tools built for paid social, Exerta included, moderate and reply to comments across many accounts at once instead of acting on one profile at a time. They sit alongside Restrict and Block rather than replacing them for personal use.
