Anyone faced this Instagram error before?

Hey guys,
So an escrow service I tried to use to buy an account from someone messed something up and now the account I wanted to buy shows a strange error when logging in.




Anyone else who have seen this error before?The "get help logging in" button only leads to a troubleshooting page.

Thanks in advance.

I have seen it before, on a very old account. When trying to login, didn't have a solution back then. If you have the original email, you could try a my account has been compromised report.
