Yes, I know of a guest house owner in Udon Thani who made all of the contacts with farangs for a number of Thai ladies who do not know enough English to read or write messages. Two I know personally were coached to get the farang to buy an engagement ring, a house and numerous other items. The guest house owner had profiles of these two girls posted on Cherry Blossoms, Thai Love Links (3 different profiles) and EuroAsia or AsianEuro (2 profiles).
Of course we stayed at the guest house of this lady.
In other words, we were actually corresponding with the guest house owner, not the two ladies although they got a summary of our e-mails, and had some input into the responses.
By the second day, the guest house owner was trying to inform us that we would have to pay sin sodt of 1,000,000 baht to the families of the two women to marry them. I have lived in Thailand for a few years and told the lady I would pay nothing. Actually, the guest house owner would take 800,000 baht of that total. The lady I had met was not ready for marriage and either was I. My friend told the guest house owner to marry me because she would not until she got to know me for a few years.
Consequently, my friend was harassed for a number of weeks by the guest house owner to get some money for her services. She got nothing. But she did tell all and sundry that my good friend was a very bad woman with no sense of morals and responsibility. She even brought in a government employee to inform me of the bad habits of my girl. However, his credibility was shot early on when he told me that as a government employee he really cares for the people, and always supports them through his honest and non-corrupt habits. The next day my friend called him and told him to speak directly to her if he wanted to say something rather than speak behind her back. She called him a sissy. Apparently, he had tried to date her a few times and she had refused.
In any case, the harassment by the guest house owner halted only after I said I was fed up with the girl and was leaving Udon. In fact, I just moved to another hotel and me and my friend are seeing one another still.
The guest house owner quickly moved me from a large and comfortable room to a very tiny room.
The other couple were even harrassed for a longer period of time. The guest house owner was sending e-mails to the guy in the U.S. condemning the young lady over a year later, and telephoning his girl friend and demanding money at the same time.
So beware internet cafe owners. They do provide a service to many of these ladies who do not speak, read and write anything but Thai and possibly Lao. However, they are responsible for putting a lot of inconvenient ideas into the heads of the Lao/Thai ladies, and are quite happy to play you for as much as they can get. The actual sites, ThaiLoveLinks, Cherry Blossoms, DateinAsia do not make any money, so far as I can tell from any relationships that develop.
By the way, when I meet my friend again in August, we will have known one another for over two years.
