There is no username, because when you register you have to give your mail and phone number, and you are assigned an account id after you create an account. they can find my account by my mail.
The outcome of the investigation is here. "The user is completely blocked for violating the company's rules. All questions can be asked by mail
security@1win.sociall". I told him to contact them through email.
What could be the violation? he's going to find that out after contacting the support of 1win. That's an interesting thing that we always get to see users complain and after investigation's conducted, they're concluded that something wrong was done. But I am sure that he's got some defense on it and he can just exchange the conversation in the email, good luck.
