So you're maybe thinking "Instagram must have a process for this, something you can do when your account is hacked?" and the answer is... kinda, but also it's completely useless. You follow the account hacked form on the website and it just endlessly redirects you to the "I need help logging in" page. If I follow the "I can't login" process for the handle they stole Instagram wants me to enter a previous password for the account, which I can't do because it's brand new (I tried). [12/16]
