As mentioned in this report, it is indeed nearly impossible to proof who ''hacked'' these accounts.
This job was purchased at a service provider by a customer. This provider outsourced the job to @Angel1223 (the customer was aware). Angler1223 then outsources this order to @Baba negra
It's likely @Baba negra didn't even complete all these accounts himself but outsources some of these accounts to others as well. On top of this, the original customer isn't even the OO as he purchased these accounts from soneone else.
Meanwhile, these accounts had no e-mail registered meaning anyone with the account info could set an e-mail and change the password. At this point far too many people have had access to the account details and we can't possibly proof who set e-mails and changed the passwords. The only thing the original customer can do here is contact the seller of these accounts to attempt recoveries, or attempt recoveries with the current available info.
@Angel1223 you posted some screenshots of other people making accusations (in a deleted post). They are free to make a report themselves.
