Tumblr is a great tool for connecting with other people with similar interests, but you may come across users on the blogging social network that you'd rather avoid. Fortunately, Tumblr allows you to block other users so that they cannot see anything you post and vice versa. You should also know how to unblock someone on Tumblr in case you later change your mind.

Instructions in this article apply to the web version of Tumblr and the Tumblr mobile app for iOS and Android.

How to Block Someone on Tumblr on the Web

To block another Tumblr user using the Tumblr website:

Find a post from the user you wish to block on your Tumblr dashboard and hover your mouse over the their profile name.

If the user hasn’t posted anything recently, you can search for them via the search bar at the top of the screen.
A small version of their profile will pop up. Select the silhouette icon next to the user name and choose Block from the drop-down menu.
Select Block again to confirm.

How to Block Someone on Tumblr for iOS and Android

Blocking someone on the official Tumblr smartphone app is very similar to how it's done on the web:

Go to the Tumblr profile page of the person you want to block and tap the silhouette icon in the menu at the top of the screen.
Tap Block in the menu that pops up.
The Tumblr app will ask if you're sure you want to block the person. Tap Block once again to confirm.

What Happens When You Block Someone on Tumblr?

Blocking someone on Tumblr hides their content from your dashboard and makes it impossible for them to see your posts or contact you. Here's what happens as soon as you block a user on Tumblr:

Your account will automatically unfollow their Tumblr blog.
Any posts of theirs shared by people you still follow will be hidden from you.
They won't see your posts in their timeline either directly or if shared by someone else.
They won't be able to send you a message or any other sort of communication on Tumblr.
They won't be able to search for you on Tumblr.
They'll be unable to share, like, or comment on your posts.

Blocking must be done on a per-blog basis, so if you have a Tumblr account with multiple blogs, then you'll have to block the user from each one.

You can still see content posted by blocked users by directly visiting their Tumblr blog.

Can People on Tumblr Tell They've Been Blocked?

Tumblr users do not receive a notification informing them that they've been blocked. They'd only be able to tell if:

They notice your posts no longer appear in their Tumblr timeline.
They try to send you a DM and can't.
They visit your profile and realize they can't comment on or share any of your posts.
