I am selling a digital product that I do not want to be shared all over. Do any of the download sites allow a one time use download link or anything of that nature? What I want is to provide the link once and after someone has used it to get the item, it can't be used again at all. I know "delete the file after it's used" a sort of solution but say I have someone affiliates selling my product and when they sell, they provide the DL link to someone. That means both the affiliate and the person they sold to will have it for x amount of time. I want to be able to say to the affiliate. Don't use it yourself or you won't be able to provide it to the buyer. Is there any way to do this?
