There are a few things you can do to determine who is behind an Instagram account. First, look at the account’s bio. This will list the name of the person or company that created the account and will also give a brief description of what they’re up to. Next, look at the posts. This will give you a good indication of who is behind the account and what they’re posting. Finally, look at the followers. This will give you an idea of how popular the account is and whether or not they are following any other accounts.
