The OP could be right on the money about it, but it doesn't matter at all. I will tell a little story to illustrate what it all means.
There is a popular teacher here, it doesn't matter where, just here. He isn't popular with the other foreigners, but he acts like a 16 year old and the students like it or so it seems. (If you are curious, he is a poster over at the Ajarn.com forum.) The first time, I was approached by someone I trust completely, and told that this friend was uncomfortbale with the teacher taking a 16 year old student(from another school) out on dates, including movies, MK, etc, etc. I talked to the teacher and he assurred me none of it happened. I reminded him that it was not good for teachers to date young students.
Fast forward then 6 weeks, someone who I trust very highly came to me and provided me information directly from a student about this teacher's escapades with the student. The student then talked directly with me and showed emails and sms messages this teacher was sending her. She had been in love with the teacher but then he found a new girl and broke up with her. She was in tears over it all. I confronted the teacher again with information. He had continued the relationship for 6 weeks after I confronted him about the issue. Including trying to force the girl to have sex with him.
I had a talk with several people in the office about what should happen. He is well liked in the office so I became ostracized in the office. As one Thai staff member said, "This girl likes foreigners, she shouldn't go out with foreigners, it is her fault." Blame the girl, not the pedophile. I confronted the teacher again. I took the advice of another Ajarn.com poster who works in the office and that since he did break it up, I should just let the teacher be and only if he does something again should I bring it up to the principal and program director. Nothing was done about the situation.
In the intervening two months since that happened, I have had my name slandered around town as a bad teacher, as a bad person. How do I know this? Several people have come to me directly and told me what they have heard this teacher say about me. The person whom I trust completely, my wife, has had rumors spread about her throughout the city as well, he has referred to her as a slut, a bad woman, etc.
A few days ago, I learned that he was involving himself with yet another student, this one 15 years old. Saw the SMS messages with my own two eyes. So I went to the director of the program, she said, "I will think about this and later I will remind him not to date students."
That's it. A smart administration would let him go now, at the end of the year. Tell him to go on his way, but instead they keep him. It is all about money, and making more of it.
Another valuable lesson was learned that showandtell would do well to heed, if you try to push this, you will be ostracized, you will be forced out a job and you will realize that Thai administration doesn't really care about keeping kids away from predators.
