X calls the keyword control Muted words. It filters matching content in the places you select. It does not stop a person from posting the word or remove every occurrence across X.
Choose words, accounts or conversation controls
Mute a word for a topic or spoiler. Mute or block an account for an account-level problem. Use conversation or notification controls when the problem is a specific thread. These actions have different effects; a keyword filter is not an account block.
Check the muted-word settings
Open X’s muted-word controls under privacy and safety, add the term and review the selected timeline, notification, audience and duration options. Use the step-by-step mute guide for the full setup. Confirm that the term is still listed after saving.
Test the actual term
For an event spoiler, start with its distinctive title and common abbreviation rather than a broad word such as “final.” X documents case-insensitive matching and explains how muting a word affects its hashtag. Review punctuation and spelling variants. A phrase in an image or video is not necessarily searchable text for the filter.
If you still see the word
- Identify where it appeared: search, home timeline, notification or message.
- Check the selected scope and whether the mute expired.
- Compare the actual spelling, abbreviation or hashtag.
- Check whether the text is inside an image, video or quoted material.
- Use a separate account or conversation control if the issue is a person rather than a term.
X’s muted words do not promise to remove matching search results or messages. Browser extensions are local filters with separate permissions and maintenance needs, not a universal account setting.
