Yes I live in India , which is more or less a low tier country compared to US , UK. It was exactly during 2019 , I was receiving many surveys when I shifted myself to a new city.The truth about survey sites is that they do send surveys to people living in Tier 3 countries but they stop sending surveys after sending two or three surveys. Do you reside in a Tier 3 country? When was the last time you received surveys from such sites?
