I would say that the men wouldn't mind being chased. But, just as women have the right not to reply to those they're not interested, men have the same right. I try to answer most emails. But, if I don't see any possibility at all, I'm likely not to.
Sometimes men will make the first move cause they like something they see in your profile. Really? Actually it is the same almost everywhere you go on the web. If you ladies see something you like it is very common to send him an introduction. Let him know you are interested. SO WHAT LADIES! Guys love the attention too! Don't wait! cause we all know when ladies like a guy they will claw and scratch at eachother to get his attention, no matter how much he says or pretends he is worth. Personally if she doesn't have current information and a current picture, within 3 months in her profile, I move on.
On non-millionaire sites, the men initiate contact. On millionaire sites, the women should not hesitate to send a millionaire an email. Sometimes they respond, sometimes they don't. But don't afraid to send an email if you find someone that interest you.
Theres nothing wrong with the women making first contact. Maybe you see someone who hasn't run across your profile yet, so why not contact him.
The other thing is, there are alot of people who have a profile on here, are looking around,, but aren't members. So, if you happen to wink at one of them, they can't reply unless they join,, the only thing they can do is wink back or make you a favorite.
