I joined Russian Brides and quickly received 500 mails from the most beautiful women you could wish to see. I decided, against my better judgement, to buy some credits. You can send emails for free but you have to pay with credits to open the replies... and believe me they will reply. 20 emails later, I realised that the replies were sometimes accurate and sometimes vague and generic. I offered to meet her, she said yes but next year when they have holidays. She then wrote to me asking me when I have a holiday! Does not make sense. The same girl... 20 emails later and asking me when I am having a holiday yet we'd supposedly arranged to meet in January 2015. Just one example of many I could quote... but I hope you get the point!
I conclude that they are paid commission... and "they" could be anyone! A little old bloke in a room who is masquerading as a beautiful young bride. It's a scam! Save your money!
