When you post on Threads, you can decide who can reply to your thread. Two of the most common reply control options are “Profiles you follow” and “Mentioned only.” Many users confuse these two settings or do not understand how they affect visibility and engagement. This article explains the exact difference between these two reply controls, how to set each one, and what happens when people try to reply to your post.
Key Takeaways: Threads Reply Controls Explained
- Profiles you follow: Only accounts that you follow can reply to your thread. Others can see the post but cannot reply.
- Mentioned only: Only accounts that you explicitly mention in the post with an @username can reply. No one else can reply.
- Changing reply control after posting: You can edit the reply control on any existing thread by tapping the three-dot menu on the post.
What Each Reply Control Does in Threads
Threads gives you four reply control options when composing a post. The two most restrictive options are “Profiles you follow” and “Mentioned only.” Both limit who can reply, but they work in different ways.
Profiles You Follow
When you select “Profiles you follow,” only accounts that you currently follow on Threads can reply to your thread. This includes public accounts and private accounts you follow. Anyone who you do not follow sees a message that they cannot reply. They can still view, like, repost, and quote the post. This setting is useful when you want to keep the conversation within your existing network.
Mentioned Only
When you select “Mentioned only,” only accounts that you tag in the post itself using the @ symbol can reply. For example, if you write a post that mentions @exampleuser, only that account can reply. No other account, including accounts you follow, can reply. This is the most restrictive reply control. Use it when you want a very targeted conversation with specific people. You can mention up to 10 accounts in a single post.
How to Set Reply Controls When Creating a Post
- Open the compose screen
Tap the plus icon at the bottom of the Threads app or tap the pen icon at the top of the feed. - Write your post
Type your text, add images, or attach a link as usual. - Tap the reply control icon
Look for the speech bubble icon with a number next to it. It appears below your text area. Tap it. The default is usually “Anyone can reply.” - Select your option
Tap “Profiles you follow” or “Mentioned only” depending on your goal. - Post the thread
Tap the Post button. The reply control icon now shows your selected setting.
How to Change Reply Controls After Posting
You can change the reply control on any post you already published. This is useful if you want to open or restrict replies after seeing the initial response.
- Find your post
Go to your profile and tap the post you want to edit. - Tap the three-dot menu
Tap the three horizontal dots in the top right corner of the post. - Tap Edit reply controls
Select this option from the menu. - Choose a new setting
Tap a different reply control option. - Tap Done
The change takes effect immediately.
What Happens When Someone Tries to Reply
The behavior depends on which control you set. If you use “Profiles you follow,” a user who does not follow you sees a grayed-out reply box with the message “Only accounts @username follows can reply.” They can still use the like, repost, and quote buttons. If you use “Mentioned only,” a user who is not mentioned sees “Only accounts @username mentioned can reply.” The reply box is disabled. Mentioned users see a normal reply box.
Common Mistakes and Limitations
I selected “Profiles you follow” but someone I do not follow replied
This can happen if the person was mentioned in a reply to your post. Reply controls apply to the top-level post only. If someone you follow replies and mentions another account, that account can reply to the reply even if you do not follow them. To prevent this, use “Mentioned only” on the top-level post.
I cannot change reply control on a post that already has replies
You can still change the reply control on any post regardless of whether it has replies. The change only affects new replies going forward. Existing replies remain visible.
“Mentioned only” blocks all replies except mentions
Even accounts you follow cannot reply. Only the accounts you tag with @ can reply. If you want to allow replies from your followers, use “Profiles you follow” instead.
Reply controls do not affect quote posts or reposts
Anyone can still quote your post or repost it regardless of the reply control. The setting only blocks replies directly on your thread.
Threads Reply Control: Profiles You Follow vs Mentioned Only
| Item | Profiles You Follow | Mentioned Only |
|---|---|---|
| Who can reply | Accounts you follow | Accounts you mention with @ |
| Can accounts you follow reply | Yes | No, unless mentioned |
| Can mentioned accounts reply | Only if you follow them | Yes, always |
| Visibility of post | Visible to everyone | Visible to everyone |
| Best use case | Keep conversation within your network | Targeted discussion with specific people |
You now understand the exact difference between “Profiles you follow” and “Mentioned only” in Threads reply controls. Use the compose screen or the edit reply controls option to change settings on any post. For the most restricted conversation, combine “Mentioned only” with a private account. A tip: if you want to allow replies from a wider audience later, change the setting to “Anyone can reply” after the post is live.
