My impression is that the situation in Thailand is under control in that the bars catering to this sort of thing have clearly moved underground as they are no longer operating with impunity.
I recall a bar in sunnee, had to go up a flight of stairs, where clearly the scantily clad hosts were underaged. This particular bar closed down some time ago. So if this sort of thing exists it is no longer out in the open.
Some hotels in Thailand even have signs at reception warning guests that they will report this sort of thing, so clearly the permissive attitude that once existed has changed.
Maybe this organization can try to help the situation in Brazil where this sort of thing is sadly rampant.
