Is there any way to find out whether a male member who once sent me an offer has left the club or is still active?

Maezawa from the Corporate Planning Office here as well. Even if you ask about information like that, I can’t tell you. That said, I think there may be ways to find out if you phrase your question creatively. It might be worth thinking through various approaches. There’s a famous riddle along those lines: (The details differed slightly from the version I knew, but the basic idea is the same.) It’s famous because, if you think it through properly, you can arrive at the correct answer. I believe it’s a problem that can be solved mathematically. If you can come up with a question like this, you may sometimes be able to determine whether the other person is still a member. There are two roads: one leading to heaven and the other to hell. Identical-looking gatekeepers stand in front of the doors to each road. You need to ask one of them for directions, but you may ask only one question. One gatekeeper always tells the truth, while the other always lies. What should you ask to find out which road leads to heaven? *Assume that both gatekeepers know which door leads to heaven and which leads to hell.
