A friend got slapped with a fine over this. He's a foreign resident, and he changed hotels while on a trip. That information is bundled up and sent to the authorities, and they cross-checked him with the address he put on his travel form. Thousand baht fine.
FWIW, I brought this same friend to the police station where I'm a registered resident in Shanghai, so he could stay with me on a 72-hour visa. At the airport, he was told that if he doesn't register and it's discovered, it could affect his ability to get a visa in the future. This was only a few months ago.
When his fixer Dith Pran died, the NPPA magazine News Photographer talked about Schanberg's reporting and how it placed you on the bridge when the Khmer Rouge entered Phnom Penh -- and how today, the first graf is the news and the second graf is reaction, followed by forward analysis.
The general complaint is that Cambodia is under Vietnamese influence, mostly stemming from its backing of and leading the defectors who overthrew the Khmer Rouge. People today complain that the top govt officials are still Vietnamese, whether by backing or by blood, as well as many of the richest tycoons; the primary deputy prime minister (there's plenty) Sok An is often called a slave to Vietnam, and he's in charge of the Apsara Authority, which manages the Angkor complex; Sok Kong (unrelated), is one of Cambodia's richest men and ran the conglomerate that held ticketing rights to Angkor for decades; he is ethnically part Vietnamese, and because Angkor's tourism revenue was suspected to be too low, complaints about the national landmark being sold off to Vietnam were so huge that it factored in the last general election. An age-old cultural hatred is at play here, which itself comes from old empire stuff.
I was once talking to Dougald O'Reilly, an archaeologist from Australian National University who's done a lot of research at Angkor Wat. He was talking about having just published a paper about a dig and centuries-old skulls they'd found, and a lot of technical data. He ended with a quip that it was a lot of head trauma, and, me not being a science guy at all, I thought he meant the paper was academically rigrous. No, every skull had had their heads bashed in.
>> I wonder if it will accelerate the pace of restoration of temples in the area.
Likely not; current restoration projects are a shitshow, with an utter lack of coordination and even communication between the various country teams involved. In one temple, the Indian team tried to clean a wall and stained it; the Chinese restoration crews make the plainest and cheapeast concrete fillers to plug gaps in rock faces, they flake if you touch them. And now, the authority in charge of maintaining the complex is struggling with how to balance the much-valued tourism with air pollution; UNESCO has threatened status and funding if it doesn't address the impact that mostly auto/bike exhaust is having on temple faces. Other restoration projects will only get initiated if someone else is spending the money, and also kicks back to Phnom Penh.
>> to the point where they filmed Indiana Jones there!
Alongside Indy, Lara and Tony Leung, my favorite film reference is at Beng Mealea, and bonus points for the article for mentioning that temple. It's about 45km away down a dusty rutted road, and before it was added to the ticket list, the only people who visited besides domestic tourists were Japanese, because Hayao Miyazaki took it as inspiration for the setting "Laputa: Castle in the Sky." If you ever saw the old Japanese tourism books with the blue outer edge, Beng Mealea was mentioned in that, and every non-Khmer there would be clutching it.
You could search PGP keyservers for email addresses/domains of the local media where that retirement fund is located and take it from there, using your own judgment about the reporter and outlet, and how much you'd want to mask that communication.
