I currently have 1150/2500 to get free premium. All that is left for me to do that is free is completing the surveys and downloading those games for 100+ credits. Are they safe? because these surveys take forever!
I don't know. define safe. i think the survey guys want to get your name, adres and living place. considering you are from the usa, you should more easely fit the profile then a different(smaller) market. i like my privacy, the little i have, but often its easy free credits
