We hate to repeat ourselves, but we’re going one more time. The success of recovering a hacked Instagram account depends on how fast you act. Remember that once the hacker has changed your recovery email, there’s practically nothing to do—and it usually took them days to figure it out.
Also, keep in mind that the hacker won’t stop with just your Instagram account. In fact, they often use Instagram as a mere steppingstone to steal your information, so they can hack your email, your bank account, etc.
On the contrary, if you can get your account recovered quickly, they will be shocked. If they sent you an email, you could email them back once your account is recovered and tell them that you get help from a cybersecurity team that’s now tracking their location. We guarantee they will stop bothering you for good.
