This is about a man in his 50s whom I met through an app before.

I’m Kazu, a male member. Reading Riichi’s answer reminded me of something. When meeting women through dating sites, I used to bring nothing but my phone, car keys, a few tens of thousands of yen in cash, and condoms. I never brought my ID or any cards, since they could be dangerous. Like men who do three-ways, I also hid a 10,000-yen bill under the insole of my shoe. I believe dating sites and apps require that level of caution. I don’t take such precautions with a dating club. In the unlikely event that something happened, I’d probably need to file a police report or something similar, but the club could identify the other person if contacted. As for your question, I don’t think such men are around in the first place, but I can’t say with absolute certainty that there aren’t any men who might make that kind of mistake. Still, with a dating club, you could at least show the screenshot to the club and have them flag him as that kind of man.

I’m だて◎ゆめ, a male member. Basically, everyone has their pride. That can easily turn into an inflated opinion of oneself, too. It’s important to have confidence, but I hope people recognize that their worth is ultimately judged by others. At a dating club, both men and women are registered with the club, so I doubt something as frightening as this would happen. When someone intends to act maliciously, they’ll try all sorts of methods, so it’s true that you let your guard down a little. I also thought that a woman who keeps sending persistent LINE messages must be attractive to men. For now, I think the best course of action is simply to ignore her and stay silent.
