What Does User Not Found on Instagram Mean?

Have you ever seen a message that says "user not found on instagram"? It can be pretty confusing, but it means that Instagram couldn't find the account that you're trying to follow.

Here are the main reasons which can cause this issue:

-The user has deleted their account (they do not exist on Instagram anymore).

-The user changed their username or handle (the name they use to identify themselves) and did not tell Instagram about the change.

-The user has been banned for violating the terms and conditions of Instagram.
