I lean towards scam too, and I'm pretty sure, because I could compare it with a legit site

Real girls on a legit site act differently: they aren't online 24/7, they don't want to chat for 4 hours and they are ready to meet pretty soon. None of that on Asiacharm, on the contrary, all they want to do is chat with you so that you keep spending your money, apparently they get a certain commission from what you spend in chat.

Guess who wrote their own glowing reviews. Go ahead, spend $70 or $150 and see for yourself. Just give me half of your money for the real correct info...

Read the reviews for VictoriaHearts, which is sister of AsiaCharm.
Personally I think both are scam.

In the past year, 1,000 girls in their 20s have written to me on this site and are falling in love with me. I'm in my 80s and have never written back, but their emails keep coming. This site is a total scam.

Experience with this and other sites like it show me this and other sites are really a rip off. The better the girls do in talking with many men the more money they make.
