Please note that by default, anyone can view your photos. If you would like to make sure only your followers see your photos, turn on private photos. Once you turn on privacy, anyone who wants to see your photos will have to send you a follower request, which you can then approve or deny.
To block or unblock someone:
- Go to their profile by tapping
at the bottom of the app and searching for their name or username - Tap
in the upper-right corner of their profile - Tap Block User or Unblock User
When you block someone, that person can't view your photos or search for your Instagram account. People aren't notified when you block them.
Yes, someone you blocked can mention your username on Instagram and this mention will appear in your News Feed. If you block someone and then change your username it will prevent them from being able to @mention you.
After you block someone, their likes and comments will not be removed from your photos. You can delete their comments manually.
If you have mutual followers the blocked user will still be able to see your likes and comments.
