Like most messaging apps and most social media, Instagram offers the ability to block other users and unblock previously blocked users. This is possible either on the mobile application or on the website. If you are being harassed by someone who creates new accounts every time you block them, you can report it and make your account private. You cannot unblock yourself from another user's block list.

Advice
- It's always best to make your account private so that anyone who wants to see your photos will need to send you a subscription request first.
- Blocking someone in the Instagram app also blocks them on the website. This also applies if you unlock it.
Warnings
- The blocked user will still be able to open another account to view your photos.
- Unblocking someone will not reactivate their account subscription and they will also be able to see that you have removed them from your subscriber list.
