It's good that you reported them If you want to help speed up the process, the best thing you can do is letting the copyright owners know, they can get it dealt with with high priority. Calling them out publicly is not the right way to go about this as you're only encouraging harassment.
Just had a thought (for everyone who reads this and wants to help out).
You can actually try and track down the original owner by Google searching the image. You can then link them to the page and encourage them to complain about the theft. dA will have to remove the image, or risk getting sued.
