As with essentially any business model, there will always be flaws. Usually, as is the case here, the flaws are human in nature - we have free will. Geordie, I wish I could tell you why your lady behaved the way she did, but only one person knows why, and it's her. If she won't answer questions about it, then nobody will know.
I think that I can see where you are coming from in saying the ladies get a kick back from EMFs, but I am confident the ladies I write to are not. On top of that, there are several instances of ladies being required to pay fees for meeting people in person, marrying, moving to direct contact, etc. Would the agency give kickbacks to ladies, and then make the ladies pay them large sums of money to use the service? It doesn't make full logical sense to me, so I'm trying to understand the hows and whys like Vince. I have a very logical frame of thought, so things need to line up for me a bit.
Another theory (even though it's far-fetched) sheds a more positive light on the lady. What if, during her broken-english phase, she was being monitored by the agency? What if they would only "allow" direct communication on a limited basis for her until she paid them a fee? Perhaps there was a different fee amoutn based on poor english ability vs. good english ability, as a "poor" amount of english knowledge would almost be insurance that the lady would require more EMF services? I don't know the lady you were speaking to, you would know her better than any of us, and she would be the only one to truly know why she behaved in that manner. You may also wish to check the brotherhood thread to see if she was talking to anyone else.
