Step 2: Tap your Threads Profile
In the bottom left corner of the Threads app menu, tap the icon that looks like a little person to head to your Profile.
Step 3: Open Settings
Tap the two lines in the top corner of your Profile page to bring up Settings.

Step 5: Tap Threads and replies
Step 6: Change your settings to “From people you follow”
Toggle the settings from “Everyone” to “From people you follow.” You can change this for First threads, Likes, Replies, Mentions, Reposts, and Quotes. This won’t change the entire feed to only people you follow, but you’ll see a lot more content from people you do.
