It might be easier to go through them if you change the licensing templates so that they add an appropriate category to the image. For example adding  to the template's code will cause the category "PixelFed copyrighted images" to be added to all images using that template. (It could take 24 hours for the categories to be updated.) Then you could browse the new copyright categories looking for images that don't belong, and use Special:UncategorizedFiles to search for images that aren't using any of the copyright templates.
