“To moderate replies on Threads, use the app's native controls: set who can reply when you post, filter replies with Hidden Words (custom and offensive-term filters), hide individual replies on your own posts, and mute, block, or restrict accounts. Because Threads is part of Meta, its Hidden Words settings work much like Instagram's. FeedGuardians does not yet support Threads, so use these native controls for Threads while FeedGuardians keeps your Instagram, Facebook, TikTok, and Bluesky comments clean automatically.
When you create a thread, tap the reply-control option to choose who can reply: Anyone, Profiles you follow, or Mentioned only. Limiting replies on launches and sensitive posts is the fastest way to cut down on spam and pile-ons before they begin.
You can change the reply audience after posting from the thread's menu if a post starts attracting unwanted replies.
Go to Settings → Privacy → Hidden Words. Turn on Hide replies to filter the default list of offensive terms, and add your own custom words, phrases, and emojis. Replies containing those terms are automatically moved out of view into a hidden section. Threads shares this system with Instagram, so you can align both.
Hidden Words only matches the exact terms you list. Spammers evade it with misspellings, spacing, and emojis, so treat it as a baseline rather than complete protection.
On any reply to your own thread, tap the menu and choose Hide. The reply is removed from public view and grouped with other hidden replies, where you can review or unhide it later. Hiding does not notify the person who replied.
For a persistent problem account, open its profile menu. Mute removes them from your view, Restrict limits their interactions without alerting them, and Block prevents them from interacting with you at all. Restrict is useful for handling a difficult commenter without escalating.
What we see go wrong most often — and how to sidestep each one.
Hidden Words is a keyword filter that misses misspellings, emojis, and scam links with no banned word. Use it as a baseline and combine it with reply controls and manual hiding.
High-reach threads attract the most spam. Setting the reply audience before posting prevents most problems.
Your Instagram Hidden Words list and several safety settings carry over to Threads. Keep them aligned so both surfaces are protected.
Hiding a reply removes it from public view without notifying the user, which avoids escalation. Reserve deletion and blocking for clear abuse.

Not yet. FeedGuardians currently automates comment moderation across Instagram, Facebook, TikTok, and Bluesky. For Threads, use the native controls described above, and let FeedGuardians keep your other channels clean automatically in the meantime.
Mute hides an account from your view, Restrict quietly limits their interactions without notifying them, and Block prevents them from interacting with you entirely. Restrict is useful for de-escalating with a difficult commenter.
