Some of you guys, especially the very left wing kind; really tend to over-estimate your importance and your capabilities.

First of all, if you mentioned it to the immigration authorities, most of the workers who are likely to underpaid and quite corrupt, wouldn't give a toss. There's so many expats up to no good on a far worse level; the authorities themselves are not likely to act unless it became a national scandal. There's those who go for the underage hookers or sell drugs, such people are far more likely to be of greater interest, for it is they that actually destroy the country and ruin so many lives.

Secondly, you'd probably have to target real working class Thai people to create a level of anger on the type of scale that would justify such action. I severely doubt that your knowledge of the Thai language or locally preferred social media outlets and other online communities is sufficient to guarantee that you could ever get a reaction at all. Not only would you struggle to reach the right people, but when you do; they probably wouldn't even understand you.

Finally, Thai people aren't quite as stupid as those in the West. As tolerant as they may be of gay and trans people; they're still fiercely nationalistic people and they do not have any kind of social justice culture like that which has been polluting the West over the past few years. A lot of them do get pissed off with bad behaviour from foreigners but they aren't out to try to catch every single naughty boy out there; some of them even profit quite nicely from their presence. Also, Thai men do like to drink, smoke, play around too, you're not likely to see them protesting against such behaviour. In fact, they may hold a more positive attitude to farang guys banging hookers rather than stealing what they consider to be 'their women.'
