Blocking a tag removes posts with that tag from your dashboard and search results
When you block a tag on Tumblr, any post carrying that tag stops appearing in your main feed, your search results, and your notifications. The posts themselves stay on the platform — the person who posted them can still see them, and other users who haven't blocked the tag will see them normally. You're just filtering them out of your own experience.
This is different from blocking a person. Blocking a tag is purely about content you don't want to encounter, whether that's spoilers for a show you're watching, a topic that upsets you, or just something you're tired of seeing.
Key Takeaways
- You can block tags directly from your dashboard by clicking the three dots on any post with that tag and selecting "Block tag".
- Blocked tags disappear from your feed immediately, but posts with those tags still exist — other users will see them normally.
- You can view and unblock your blocked tags anytime in your account settings under Blocked Tags.
- Blocking a tag does not notify the person who posted it, and they cannot see that you've blocked the tag.
- Tag blocking works across Tumblr's main feed, search results, and notifications, but not on individual blogs you visit directly.
Block a tag from your dashboard in three steps
The fastest way to block a tag is right from your feed. Find any post with the tag you want to block, then click the three dots (the menu icon) in the top right corner of that post. A dropdown menu appears with several options.
Select "Block tag" from that menu. A small window will pop up showing you the exact tag you're about to block — this matters if a post has multiple tags, because you're only blocking the one you selected. Confirm by clicking "Block" in that window. The post disappears from your feed immediately, and Tumblr will filter out all other posts carrying that same tag.
If you change your mind or want to block additional tags, you can do this same process with any post. There's no limit to how many tags you can block.
Find and manage your blocked tags in settings
To see all the tags you've blocked, go to your account settings. Click your profile icon in the top right, then select "Settings" from the dropdown menu. On the left sidebar, look for "Blocked Tags" — it's usually near the bottom of the list, under other privacy and safety options.
Your Blocked Tags page shows every tag you've filtered out, listed alphabetically. Next to each tag is an "X" button. Click that button to unblock the tag immediately — posts with that tag will start appearing in your feed again. You can unblock tags one at a time whenever you want.
Tumblr doesn't show you how many posts carry a blocked tag or give you a preview of what you're filtering out. If you're unsure whether you want to block something permanently, you can always unblock it later and see what appears.
What blocked tags do and don't filter
Blocked tags filter posts from your main dashboard feed, your search results, and your notifications. If someone you follow reblogs a post with a blocked tag, you won't see that reblog. If a tag appears in a post's caption or tags section, the entire post gets filtered.
Blocked tags do not filter posts when you visit someone's blog directly. If you go to a specific person's page and scroll through their posts, you'll see everything they posted, including posts with tags you've blocked. Tag blocking only affects your personalized feed and search — it doesn't change what's visible on individual blogs.
Tag blocking also doesn't prevent you from seeing a post if you search for something else and that post comes up. For example, if you block the tag "spoilers" but search for a character's name, a post tagged with both that character and "spoilers" might still appear in your search results.
The difference between blocking a tag and blocking a person
Blocking a tag filters content by subject matter. Blocking a person removes all their posts, reblogs, and messages from your experience on Tumblr. You won't see anything they post, and they can't message you or see your blog unless they log out.
If you want to avoid posts from a specific person but still see posts from others on the same topic, block the tag instead. If you want to avoid that person entirely, block their account. You can do both at the same time — there's no conflict between blocking a tag and blocking a person.
Blocking tags doesn't notify anyone
When you block a tag, the person who posted it has no way of knowing. Tumblr doesn't send them a notification, and they can't see a list of who has blocked their tags. The post stays on their blog and in their followers' feeds normally — you're just filtering it out of your own view.
This means you can block tags freely without worrying about hurting someone's feelings or starting conflict. Tag blocking is entirely private to your account.
Use tag blocking for spoilers, triggering content, and topics you're tired of
The most common reason to block a tag is spoilers. If you're watching a show and don't want plot details in your feed, block tags like "game of thrones spoilers" or "[show name] spoilers" — whatever tag the community uses for that show. This won't catch every spoiler (some people don't tag them), but it filters the ones that are tagged.
You can also block tags for content that upsets you or that you're trying to avoid. Many Tumblr communities use consistent tags for sensitive topics, and blocking those tags keeps them out of your feed. You can block as many tags as you need to make your dashboard a space that feels safe and enjoyable for you.
Some people block tags for content they're just tired of seeing — a trend, a fandom, a meme format. There's no judgment involved. If you don't want to see it, block it.
Frequently Asked Questions
Can I block multiple tags at once?
No, you have to block tags one at a time through your feed or your settings. There's no bulk-block feature. However, you can unblock multiple tags at once by going to your Blocked Tags page and clicking the X next to each one in quick succession.
Will blocking a tag stop me from seeing reblogs of posts with that tag?
Yes. If someone you follow reblogs a post that has a blocked tag, you won't see that reblog in your feed. The tag blocking applies to the post itself, regardless of who shared it.
What happens if I block a tag and then unblock it later?
Posts with that tag will start appearing in your feed again. Tumblr doesn't hide your unblocking history, and the original posters won't be notified. You can block and unblock tags as many times as you want.
Can I block a tag on someone else's blog to keep it out of their feed?
No. Tag blocking only works on your own account. You can't block tags for other people, and you can't see what tags they've blocked.
Does blocking a tag prevent me from finding posts if I search for that tag directly?
If you search for a blocked tag by name, Tumblr will show you posts with that tag. Your block only filters the tag from your dashboard and general search results — it doesn't prevent you from finding posts if you actively search for the tag itself.
