it is possible for someone to simply have bad luck with offers on a certain wall one day or maybe they had exceptionally good luck one day on another site . but like you said , an offer wall is going to credit the same on any site you use it on . the only differences among the gpt sites are the rate of pay for the offers and the amount of available offers . it aggravates me to no end when folks will say , well site 626 doesn ' t disqualify you as often on surveys as site 746 does or they ' ll claim one gpt site has a higher acceptance rate on a particular survey router . i am strictly talking about gptsurvey sites , not sites like mturk or prolific <| sep |> The reasoning is quite simple . Lets say you live outside of a village , and outside the village lives 9 other people . Living inside the village is 30 people . Now , you all pay a set amount into the communal chest that is supposed to pay for roads , a doctor , a policeman , etc . The village people however notice how the police is costly , they have to pay him to protect your house too . But they don ' t even live at your house ! So they take away the policeman , after all he ' s just needed in the village . That ' s the important place . And really , why should the doctor be available outside of the village ? She ' s way too important to go see you out there . No it ' s better if she just stays in the village all the time . It ' ll be cheaper and more centralized . And that road to your house , there ' s no reason that should have asphalt , and those holes in it will have to wait . Fixing them will cost money that ' s much better spent getting the city people another football field . After all they need that . What ? You don ' t want to pay into the communal chest anymore ? Not an option . All of the decisions were agreed upon . We all had an equal vote and your side lost fairly 30 to 10 .
