Post content filtering prevents posts with certain text content from showing up on your dashboard and in search.
On the web:
- Go to your Account settings (click the little human at the top of the screen, then “Settings”).
- Scroll down to “Filtering” and click the little pencil icon on the right next to “Filtered Post Content”.
- Type your text, then click “Add” to filter them. Keep in mind that you’re limited to 200 of these, and each filtered word or phrase can only be 250 characters max.
- To remove a filtered piece of text, just click the “Remove” button.
In the apps:
- Tap the gear icon to access your Account settings. Then tap "General settings."
- Scroll down and tap on "Filtering."
- Tap the +New icon to to add a piece of filtered text or a filtered tag.
- Type into the box, and hit "Add."
- To remove a filtered item, swipe left on that item, and tap "Delete."
Some things to keep in mind:
Each piece of text you add will be filtered in a “case insensitive” manner, so filtering “horses” will filter “HORSES” and “hOrSeS” in the same way. Also, these are very greedy filters: filtering “horse” will filter “horses” and “horseman” and “abhorsement” (is that a word?). If you add a phrase to your filtered list, like “horse friend,” we’ll filter out occurrences of that entire, exact phrase.
The post content we check when using your filters includes all the text used in the post, including the names of the blogs who are posting and may be in the reblog trail.
Also, we can’t filter the text inside of an image in a post; we’re not that magical (at least not yet). It’s also worth noting that post content filtering doesn’t filter out advertisements, posts sent via messaging, or your own posts. In addition to post content filtering, there’s also tag filtering, and plenty of other tools (like privacy options and blocking) for making Tumblr the Tumblr you want to see.
