Thing is, there's other nationalities who quite frankly would probably be a lot more effective at coming off as convincing to potential victims, especially given the unfortunate effect this has had on the Indian people's reputation.

The fact that we haven't really seen anything near the level of Indian call centres tells me that this is unlikely.

I'm not saying that scammers don't exist in other countries, but that it's very rare to see anything with the level of sophistication and organisation that we see in India.
