EXIF data is not even close to an acceptable timestamp for so many reasons.  First, sli.mg, imgur, and every other image host I know strips the EXIF info out of your images for the privacy reasons you stated. Second, EXIF data is wicked easy to fake. Just download an EXIF editor and put whatever timestamp you want in there. Third, no way @The_Penis_Wizard would want to download everyone's verification pictures and open them up in a tool to read the EXIF data. That would take forever.  Fourh, you actually told OP to delete his EXIF data for privacy reasons right after you told him to use it as proof of timestamp. Maybe you meant only the GPS part, but EXIF strippers usually clear everyt  7ff9  hing.  Paging @EDfromGuhnetiks , ignore everything this guy said except his comments about EXIF data potentially exposing your location. This is a valid concern and could save your ass later, especially if you send someone photos without using a image host. For verification, just write the date on a piece of paper. The point is to keep people from verifying with old photos.
