You cannot post PDFs. It needs to be an image file and they only support .jpg, .gif and .png. You can, however, upload the PDF to a free sharing site, such as Dropbox, and post the link to it here. (Or, you can convert the PDF to one of the valid formats.)
In addition to the information Adrian provided above, you can provide evidence through our Data Verification form here. Once submitting it will be forwarded to our editors for review. Cheers!
