Yes, same rules apply. In fact, let's be honest, I'm only assuming the men that I've encountered are single. I have no clue, some could be married or otherwise attached. As for young men, I would think it applies, granted, I'm 50 years old, young men aren't exactly knocking down doors to approach me these days. Your junk email/phishing scam analogy makes a lot of sense; damn, doesn't that make a girl feel special? ;)
