It's only ever investigated if someone complains. In all the years I've been here I only know of one case, and that's where the wife of a remote working farang was showing off to a neighbour how much her husband was making working online. In typical Thai woman jealousy, the neighbours reported the matter to immigration, who swooped on the house, confiscated the computer, analysed it and kicked the farang out with a three year ban. I tend to think the neighbour may have had friends in the police so they went to the furthest extent. That's why I always tell people to just keep their mouths shut
