you can check his wallet to see any of the transactions, maybe it belongs to another user, and uses it as a second account.

I already did it, and then I saw your comment :) It's really someone's second account.

Sure, no doubts, just whose - that is the question)

Thank you @fivefiveeleven I will try to contact anyone in his transactions

He powered down the deposit of another girl. That is why, there are so many transactions. I don't understand just why didn't he do it in one transaction.
