All of NSTT's cover uploads are scans, so (and I guess it may just be me), I fail to see what is being "proved" here.
What is the point in anyone commenting on the artistic pros and cons of a scan?
If an uploader of scans is sufficiently prolific in their uploading, they will be given "contributor" status whilever that rate of uploads continues.
Other than that, there is simply nothing to prove!
Granted, he usually post good scans, and he would slide in on that alone. The issue here is, he's requesting status based on what he submitted in this thread... and these aint scans this time. Having said that, I think his future customs will look better if the credits are not on the front of the cover.
