Version 8.4 of the iOS app brings a content filtering change with it. Previously, you would tap the little lock (the one that appeared when you pressed and dragged the filtering opens—like top, recent, etc.—to the left) to show or hide NSFW content in your search results.
Now, to show or hide NSFW content in search results:
- Leave the Tumblr app for a sec and go to the main Settings app on your device.
- Scroll down and tap “Tumblr.”
- Look for “Safe Search” and adjust it to your liking (off shows NSFW content from search results, on hides it).
Go back to Tumblr and search to your heart’s content. 👍
