I understand how you feel for getting banned on survey sites . They must have noticed that you reside in the tier 3 countries or maybe there are some questions that you answered differently.Highest I've made in a month has to be $60 which I earned from taking surveys back then. After spending some time on the site, I got to know how to earn $30 every 3 weeks but was later banned for no reason. I've gotten a job since and my activity rate slowed down in the online space.
