Half value = red flag.
But there are ways to earn 5 dollar amazon cards for free via the bing search engine.
I suspect someone has 1000 emails and with scrypt coding could earn 1000 x 5 = 5000 in cards a month.
I earn 1 every 22-28 days as does my wife.
you can earn 150+100+20 = 270 points in a day + 30 in quizzes so 300 but you need a cell phone. to get about 9000 points a month
with no cell phone 150+20= 170 + 30 in quizzes do 200 a day or 6000 points a month.
I have to think some people are earning a ton of cards via multiple emails
I earned one today with a bing account .
