Cleanfiles is a new and improved Pay-Per-Download site (PPD). You get paid when someone downloads a file that you have uploaded to their site. They have also incorporated a unique landing page for the visitors downloading file.
Before they can download your file, visitors have to complete an advertiser survey or offer. Advertisers usually pay $1.00+ per completed survey, which is then paid to you!
The best part is that it's completely free to join Cleanfiles!
