I have an instagram account that got locked out because I signed in from a new device. The email I used to register the account 12 years ago was deleted, so I'm unable to receive the security code to unlock it. This account is also apparently ineligible to ID verification because it was registered pre-facebook acquisition. I couldn't find anyone at FB/IG willing to help me with this. There are pictures of my friend who passed away years ago and apparently this is going to stay online forever...
