Sihanoukville, Poipet, and Bavet used to be packed. A few years ago, online scams brought a massive rush of people and cash to the streets, keeping local businesses humming. But after the recent major crackdown, the scammers cleared out. Now, everyday locals who made a living renting rooms or serving food to that crowd are suddenly feeling the pinch. Landlords are missing rent payments, small eateries aren't seeing those big groups of diners anymore, and the local economy has cooled right down.

Observers point out that these empty gaps need filling fast. Relying on the old, dodgy ways of making quick money is clearly out of the question—the area needs to pull in legitimate, legal investment so people can make a stable living over the long haul. That said, rebuilding investor confidence isn't going to happen overnight, and locals will likely have to weather a lean period for the next two to four years.

Walking down the street, you can really feel that everyone is trying to figure out what comes next. Sure, times are tight right now with all the shady operations gone, but it is also a chance to wipe the slate clean and start fresh. The wind is blowing in a different direction now, and whether these towns can bounce back will depend entirely on what kind of new business they can attract next.
