The below applies to my experience in New Zealand, as we are a small rock in the pacific we probably have less scammers as it's harder to scam us due to geographical location.
I joined Cupid in New Zealand a couple of years ago and found quite a few women and went on first dates with them. Yes there are scammers on the site, I came across plenty, but, it's not the sites fault, you soon find out they are fake by asking their location, then you ask them a question about their location that they should easily know. If they can't answer it, they are not from around those parts.
I was just hitting the on line people and started chatting.
And guys, if your 50+ or so, don't go thinking a hot 26 year old with a large lung capacity, and a body that works out every day, is going to want to pop anything of yours in her mouth, go for something in the ball park, not in Disneyland, you'll have less issues.
