My understanding is that those young guys in internet cafes are not all just independently doing it, but are working a job doing it. Which I guess I actually did for a summer in Canada when for two weeks I sold magazine subscriptions that also awarded prizes when you subscribed (you never got them).

There was 2-3 people who actually ran the call center and made the real money. My friend worked there longer than me and he found out their names were pseudonyms. I think they eventually shuttered the call center and disappeared one day.
