We would asume (im 90%ish sure) that the game would be sold online through a distributor. The sight would proably show how many times the game was bought and downloaded?
About this trust thing... I perfectly agree. Why would you pay someone you don't know. If you're talking to a friend and say "I'm hungry" and suddenly a stranger walks up to you both and offers "I'll go get food for you but you have to pay me" think... The distributor (you) wouldn't want to pay untill the task (food obtained) is complete... And the the stranger (I suppose in refference to this would be the scripter) wouldn't want to waste their time and efforts with the possibility that you would take advantage of them and not pay for the work...
Background Checks are a good thing :P
