Nice work putdat! I've seen a few of these lately and then I don't see them again. I feel like there has to be some sort of long term tactic employed so that you don't get run down seeking out and putting up data all by yourself. Right now I don't see any reason to upload my own datasets. For instance, could you require that in order to download unlimited data, they need to upload at least one data set? Just throwing it out there.
