Blocking users

How to block

If you receive unwanted messages, reblogs, or follows, you can block the person who's sending them. You can do so from a number of places within Tumblr.

• From your mobile or web dashboard, open the user's blog by clicking or tapping on the avatar, then go to the user menu (the little human), and select "Block."
• From your blog settings page on the web, just click the pencil to edit your blocked users then type in the user that you want to block.
• From post notes on the web, click the three dots that appear when you hover over a reply or reblog caption to bring up the block option. From the app, just tap (iOS) or tap and hold (Android) a reply or reblog caption to bring it up.
• From a messaging conversation, click or tap the three dots at the top of the screen, and choose "Block."
• From your mobile or web inbox, click or tap the three dots at the bottom of the ask or submission, and then hit "Block."
• From a push notification (for follows, mentions, or messages), tap the "Block" button that comes up when you do the following:
  • On newer iPhones with 3D Touch, hard-press the notification.
  • On older iPhones, swipe the notification over to the left and tap the "View" button.
  • On Android phones, swipe down on the notification.

(Note that if you got an anonymous ask, it may not be associated with any particular account, which means you can’t really block the person that sent it. So what you're doing when you click or tap those three dots and hit "Block" on an anonymous ask, is blocking the IP address the ask came from. Any further anonymous asks sent from that address will never see the inside of your ask box. FYI: There’s no way to unblock an anonymous IP address. Additionally, the person sending unwanted anonymous asks could still send you anonymous asks from another IP address. If you’re receiving these anonymous asks from multiple IP addresses, you can disable anonymous asks or even disable the ask feature entirely in your blog settings.)

What blocking accomplishes

When you block someone from your blog:

• They won't be able to follow your blog.
• They won’t be able to message you.
• They won't be able to send asks to your Tumblr. 
• They won't be able to see your posts in their dashboard.
• They won't be able to like or reblog your posts.
• You won't show up in their search results.

Other considerations

• When you block someone, you'll be blocking them from a specific blog on your account, not all of them. If you want to block someone from all of your blogs, then you'll have to add them to each block list.
• We don't tell people when you block them, so they will not automatically know. But they might figure it out on their own if they visit your website, try to reblog one of your posts, say, and are prevented from doing so.
• To unblock someone:
  • In the app, tap the account icon (the little human), make sure the correct blog is selected in the top left-hand corner, then tap the gear icon and look for “Blocked Tumblrs.” Or to go straight to a specific blog to unblock, type the name of that blog in the search box. Next, tap on the blog name, tap the little human icon in the upper right hand corner, and tap “Unblock."
  • On the web, go to your blog settings, scroll to the bottom, and click on the pencil icon next to "Blocked Tumblrs." From there, you can click the Unblock button next to any blocked user.
• Alternatively, you can also hide your blog from people who aren't logged in. Just head into the settings for the blog you want to hide from public view, scroll down to the "Visibility" section, and turn on the switch that says "Hide username.tumblr.com." This will make the blog only viewable within the Tumblr dashboard.
