This topic was raised exactly 2 years ago. Many were mistakenly connected to the so-called DMM sponsor account.
After trying to write to technical support, it completely ignored requests to unlink the account. After that, a rumor went around the Internet and external sources of information that DMM quoted: “We do not want to lose our “CLIENTS” who use our service.”
They meant that they deliberately ignore requests or try to keep users on their service, not giving the opportunity to unlink the account. Because of this, many suffered, which brought consequences such as blocking the Gaijin Store, the exchange and attempts to link to other services.
Gaijin, with great respect, I ask you to pay attention to this case and start acting, because users are suffering because of the Japanese service.
