i don't know, but some time back i was poached off fiance to prettyrussianbrides and she did her best to keep me on that pay site, basically if they make it difficult for you to get their email then...
I dont think anyone should pay for letters or anything there is plenty of good sites where you just pay a nominal fee per month and communicate with as many girls as you want.
I have NEVER paid "per letter", bought tokens or ANYTHING like that.
The few letters I have EVER written (and we're talking about only a handful) were written to a few women on fiance.com or luckylovers, when I would buy single month memberships in anticipation of having a few options (back ups) when I went to the FSU.
I also got a few addresses from a free site 4 years ago - but never met any of those girls either.
Kiwinorth said it for me...I'm just agreeing. Girls (or profiles of girls) are used to poach men to join other sites.
Happened to me once in the early days. She said she thought the chat facility on this other site was better.
I smelled fish then and have been smelling it ever since.
