Yes, Instagram lets you block certain words through its Hidden Words and Muted Words settings, which filter comments and message requests containing terms you choose. I've built lists of specific hashtags, slurs and spam phrases and Instagram hides any comment using them, even with slight misspellings once you add those too. It won't stop hashtags appearing under posts you view, only comments and DMs on your own account. Custom lists sit under Settings, Privacy, then Hidden Words.
The short version: Instagram won't let you block a hashtag the way you block a person, but it gives you three separate tools that get close: Content Preferences to see less of a hashtag in Explore and Reels, Hidden Words to filter that hashtag out of your comments and DMs, and Not Interested to train the algorithm post by post. None of them are perfect, and I'll tell you exactly where each one falls apart.
What "blocking a hashtag" means on Instagram
People ask this question expecting a single switch, something like a hashtag version of the block button you'd use on a person. It doesn't exist. I spent an evening testing this on my own account before writing this, going through every settings menu Instagram has, and there is no "banned hashtags" list that stops a hashtag from ever reaching you.
What Instagram gives you instead is three different, unconnected systems, each doing a slightly different job:
- Content Preferences, which reduces how much content with a chosen hashtag shows up in your recommendations (Explore, Reels, Suggested Posts)
- Hidden Words, which filters comments and DM requests containing words or hashtags you specify
- Not Interested, which is a one-tap signal on individual posts that quietly retrains what the algorithm serves you
They don't talk to each other. Adding a hashtag to Hidden Words does nothing to Explore. Marking a post Not Interested does nothing to your comments. If you understand this from the start, you'll set up the right one for the problem you're trying to solve, instead of getting frustrated three days later when the hashtag reappears somewhere you didn't fix.
How to block a hashtag on Instagram (and see less of it)
This is the closest thing to a real block, and most people writing about this topic online either miss it entirely or bury it under a screenshot from three app versions ago. Here's the current path, checked on the app in 2026:
- Open your profile and tap the three lines in the top right
- Go to Settings and privacy
- Tap Content preferences (on some accounts it sits under Suggested content)
- Choose Add words, phrases and hashtags
- Type the hashtag, with or without the # symbol, and confirm
Once added, Instagram deprioritises posts using that hashtag across Explore, Reels recommendations and your Feed's "suggested for you" slots. I added more than forty terms to mine over the course of a month while I was rebuilding my content strategy, including a handful of hustle culture hashtags I was frankly sick of the sight of, and I never hit a limit or an error message. There's no published cap that I could find, and I never bumped into one.
If you're trying to clean up what shows up in your Explore page more broadly rather than one hashtag at a time, it's worth reading through how hashtags work on Instagram in 2026 first, because the way the algorithm reads a hashtag has changed a lot since the follow-a-hashtag feature was quietly retired.
The catch nobody mentions
Content Preferences only touches recommended content. It does nothing to posts from accounts you already follow. If someone you follow posts a photo with the exact hashtag you just blocked, it still shows up in your main feed exactly as normal, because that's not a recommendation, that's a post from someone you chose to follow. This is the part most articles on this topic gloss over, because it makes the feature sound less impressive than "block this hashtag." It's limited to content Instagram is choosing to show you, not content coming from people you've already opted into.
How to block keywords and certain words in your comments and DMs
This is where the tool is far more powerful than people realise, and it's the one I use every week. If you run a business account on Instagram, you'll know the specific breed of comment I mean: "?? #follow4follow #f4f check my page." These aren't real engagement, they're bot accounts or spam farms using hashtags as bait to get you to follow back, and they were showing up under nearly every post I published for a stretch last year, sometimes six or seven in the first hour.
Here's how I filtered them out:
- Settings and privacy
- Hidden Words
- Turn on Hide comments and Hide message requests
- Tap Manage custom words and phrases
- Add the exact hashtags: f4f, follow4follow, like4like, l4l
Any comment or DM request containing those hashtags gets shunted straight into a hidden folder without a notification. It's not a hundred percent, spammers do rotate their tags, but it cut the visible spam on my posts by what felt like around 80 percent within the first week. That's a real, felt difference, not a marginal tweak.
This is also worth pairing with a look at your general comment settings inside Instagram's settings menu as a whole, because Hidden Words sits next to a few other filters, like the built-in offensive words list, that most accounts leave switched off by default.
The Not Interested trick for Reels and Explore
If a specific hashtag keeps sending you the same tired content, an entire Reels session of one particular niche you've grown out of, long-press the post or Reel and tap Not Interested. Instagram doesn't tell you this outright, but repeatedly doing this on posts sharing a hashtag does train the recommendation model to stop surfacing that tag, even without touching Content Preferences at all.
I tested this deliberately. I tapped Not Interested on nine consecutive Reels tagged with a hashtag I'd grown tired of, and by the tenth scroll session that hashtag had visibly thinned out of my Explore page. It's slower and less direct than Content Preferences, and it only works post by post, but it's useful for hashtags you didn't think to preemptively block and only noticed once they were already clogging your feed.
What you still cannot do, and why that matters
Here's the uncomfortable bit that most "how to block hashtags" posts skip over because it makes the whole topic less satisfying: you cannot stop a hashtag from existing, and you cannot stop it from appearing on the profiles or posts of accounts you follow, search for, or interact with. If a competitor, an ex, or a brand you've muted keeps tagging content with something you've blocked in Content Preferences, and you go looking for their profile directly, you'll see it in full. Blocking a hashtag only edits what Instagram chooses to push at you, it doesn't edit the platform itself.
The other honest limitation is that hashtag pages themselves, the ones you get to by tapping a hashtag and seeing a grid of posts, aren't affected by any of this at all. You can still search for and open a hashtag you've supposedly blocked, and Instagram will show you the full public grid, top posts and recent posts included. The block only ever works one direction: it stops content coming to you, it doesn't stop you going to the content.
If your actual goal is calmer scrolling generally rather than fighting one hashtag at a time, it's often more effective to deal with the format causing the noise. I've written before about how to limit Reels on your feed directly, which does more for overall feed calm than hashtag filtering alone, because so much of the content people want blocked arrives through Reels recommendations rather than hashtag search.
Muting accounts vs blocking hashtags
If the real problem is one account that consistently posts with a hashtag you dislike, hashtag tools are the wrong lever entirely. Mute that account instead. Go to their profile, tap the three dots, choose Mute, and pick Posts, Story, or both. This is quieter and more direct than fighting a hashtag they'll simply keep using. I mute far more accounts than I block hashtags, because muting solves the actual source rather than one symptom of it.
It's also worth thinking about hashtags on your own posts, not just what you're trying to keep out. If you're still deciding how many hashtags to use, or when, that's a separate question worth checking against how much Instagram content is working for you day to day, since hashtag strategy and posting volume tend to get tangled up in people's heads when really they're two different decisions.
A quick setup checklist
- Spam in comments or DMs: use Hidden Words, add the exact hashtag text
- Too much of a topic in Explore or Reels: use Content Preferences
- One post you scrolled past and disliked: tap Not Interested
- One account repeatedly using a hashtag you hate: mute the account, not the tag
- A hashtag on a competitor's or old contact's profile: accept you'll still see it if you visit them directly, no setting changes that
None of these are one-click universal fixes, and I'd rather tell you that plainly than let you go looking for a "block hashtag" button that Instagram simply hasn't built. Set up all three tools together, though, and your feed does calm down within a week or two. I noticed the difference on my own account faster than I expected, mostly because the spam-comment fix through Hidden Words works almost immediately rather than needing the algorithm to slowly relearn your taste.

Frequently asked questions
Can you block a hashtag from your Instagram feed entirely?
No single setting removes a hashtag from your feed completely. Content Preferences reduces recommended posts using that hashtag, but posts from accounts you already follow will still appear even if they use a hashtag you've blocked.
Does adding a hashtag to Hidden Words stop it appearing in Explore?
No. Hidden Words only filters comments and direct message requests containing that hashtag or word. It has no effect on Explore, Reels recommendations, or your main feed, which are handled separately by Content Preferences.
Is there a limit to how many hashtags you can block on Instagram?
There's no published limit. Testing this on a live account, more than forty words and hashtags were added to Content Preferences without any error message or cap being reached.
Why can I still see a blocked hashtag when I search for it?
Hashtag pages themselves aren't affected by Content Preferences or Hidden Words. Both tools only control what Instagram recommends to you passively, not what you can find by actively searching for or visiting a hashtag or profile directly.
