How to block someone without them knowing Instagram
Blocking someone on Instagram means that they will no longer be able to see your profile or content, and they won't be able to message you. However, they may still be able to tell that they have been blocked by certain signs. Here are the steps to block someone on Instagram without them knowing:
Open the Instagram app on your mobile device and go to the profile of the person you want to block.
Tap the three dots in the top right corner of their profile.
Select "Block" from the dropdown menu.
Instagram will ask you to confirm that you want to block this person. Tap "Block" again to confirm.
Once you've blocked someone on Instagram, they won't receive any notification that they've been blocked. However, they may notice that they can no longer see your profile or content, and they won't be able to message you. If they try to view your profile, it will appear as if your account doesn't exist.
