This is a very large number of accounts and etherum addresses. Have you ruled out these addresses belonging to an exchange?
Nope, checked.
I would advise you posting evidence you checked against things like exchanges and the like. Some will want to ensure these are not deposit addresses to xx exchange before staking their reputation that all these accounts belong to the same person.
Every exchange assign different eth address to different account, unless it is decentralized exchange which isn't case here.
