No, but if you go to a big city, like Seoul, Singapore, or Hong Kong, you'll find something close. The high population density makes it feasible.
The reason there is such a severe Korean spam problem, for instance, is because South Korea went from having no internet infrastructure to having almost universal DSL in every home, rich or poor, in the course of about three years. This is not enough time for people to understand the network, and what happened was they grew a network with very different rules than the rest of the world expects. Spam there is considered routine, and people expect to change e-mail addresses monthly. They don't even put them on business cards because they don't expect company addresses to stay the same for long.
Well, that's part of the problem. A lot of places are being broken up into haves and have-nots and very little in-between. China is perhaps the most dramatic example of this although you can see similar things in Thailand and even Korea. There are cities with very high population density and extremely powerful communications, and rural areas with very low population density and marginal to nonexistent communications. And little in the middle.
I could make an analogy with MCI "cream-skimming" but I'm not going to.
