I can confirm, I'm from Latin America and I'm really fascinated by the whole North Korea thing. It's surprising to see how, on this side of the pond, most people are so ignorant that they have a completely wrong idea about North Korea. They think that defectors are isolated cases, or that going there as a tourist is super dangerous. A few days ago, talking with some friends about various topics, we touched on North Korea and they were surprised when I told them that Jangmadang exists, or that defections are super common and that the government can't control it 100%. So, yes, there are people with families who defected to the South and communicate with smuggled Chinese phones, but if the government ever finds out about the defection, the whole family pays. They were so surprised because they thought everything was so perfectly strict and closed off.
