Spam replies clutter your Threads conversations and can expose you to malicious links or fake promotions. Threads includes built-in filters that automatically catch and hide these unwanted replies before you see them. These filters rely on keyword patterns, account age, and follower counts to identify spam. This article explains how to enable and customize those filters so you can keep your reply threads clean.
Key Takeaways: Using Threads Built-In Spam Filters
- Settings > Privacy > Hidden Words: Lets you add custom keywords and phrases that automatically hide replies containing those terms.
- Settings > Privacy > Muted Accounts: Hides replies from accounts that are new, have few followers, or match other spam signals.
- Settings > Notifications > Replies: Filters which reply notifications you receive based on account age or follower count.
How Threads Filters Spam Replies
Threads uses two main systems to detect and hide spam replies. The Hidden Words feature scans reply text for specified keywords, phrases, and emoji. Any reply containing a blocked term is automatically hidden from your view. The Muted Accounts feature examines the replying account’s age and follower count. Accounts created recently with few followers are more likely to be spam and can be muted automatically. These filters work together to reduce the manual effort of reporting spam.
The filters apply to all replies on your posts. They do not delete the replies. Hidden replies are stored in a separate Hidden Replies section that you can review at any time. You can unhide a reply if the filter caught a legitimate comment by mistake.
Steps to Enable Hidden Words for Spam Detection
- Open the Threads app and go to your profile
Tap your profile picture in the bottom-right corner of the screen. - Access Settings
Tap the two horizontal lines icon in the top-right corner, then select Settings. - Navigate to Privacy
In the Settings menu, tap Privacy. - Select Hidden Words
Under the Privacy section, tap Hidden Words. - Toggle on Hide replies that contain certain words
Enable this switch to activate the keyword filter. - Add spam keywords
Tap Manage Words and then tap Add Word. Type a keyword like “free money” or “click here” and tap Done. Repeat for each term you want to block. - Add spam phrases
Tap Manage Phrases and then Add Phrase. Enter a full phrase such as “check out my profile” and tap Done. - Block spam emoji
Tap Manage Emoji and then Add Emoji. Select the emoji you want to block. Common spam emoji include the money bag, rocket, and pointing hand.
Steps to Mute Accounts Based on Spam Signals
- Go to Settings > Privacy > Muted Accounts
Follow the same path as above and tap Muted Accounts. - Enable mute for new accounts
Toggle on Hide replies from accounts created less than 24 hours ago. This blocks spam bots that post immediately after sign-up. - Enable mute for accounts with few followers
Toggle on Hide replies from accounts with 1 or fewer followers. Adjust the threshold if needed. Accounts with zero followers are often spam. - Confirm your changes
Tap Done in the top-right corner. The filters activate immediately.
Common Issues After Enabling Spam Filters
Legitimate replies are hidden by the filter
If a real reply contains a blocked keyword, it will be hidden. To review hidden replies, go to your post and tap the speech bubble icon. Then tap Hidden Replies at the top of the reply list. Tap Unhide next to any reply you want to restore. To prevent future false positives, remove the offending keyword from your Hidden Words list.
Spam replies still appear in notifications
The Hidden Words and Muted Accounts filters only hide replies from your post view. They do not affect notifications. To reduce spam notifications, go to Settings > Notifications > Replies and toggle on Filter replies from new accounts. This prevents push notifications for replies from accounts that are less than 24 hours old.
The Hidden Words list does not apply retroactively
Filters only apply to new replies posted after you enable them. Existing replies that contain spam are not hidden. To clean up old spam, manually delete or report those replies. Tap and hold a spam reply, then select Delete or Report.

You now know how to enable and customize Threads built-in spam filters. Start by adding common spam keywords and phrases to the Hidden Words list. Then enable the Muted Accounts settings to block replies from new or low-follower accounts. For more precise control, review your Hidden Replies folder weekly to catch any false positives. Adjust the keyword list as spam tactics evolve. This layered approach keeps your Threads conversations focused on real engagement.
