I found this out when I was searching for niches for YouTube+PPD. If you want to take a stroll through the files at Cleanfiles for ideas, check this out. Put in a url, for example http://cleanfiles.net/?27465 Then just change the numbers. http://cleanfiles.net/?27464 You can make an imacro to do this for you pretty quick, then just take a stroll through the downloads and pick what you want. You can do the same thing with other sites, even ones that use letters as "random" urls. Enjoy!
