So, I guess one of my recent uploads, https://wallhaven.cc/w/j5pjx5, was a bit lower quality than the standards here (it was a high-res image, but yeah, on further inspection, it WAS a bit grainy, oops).
It was also in the wrong category, which was a simple misclick. I apologize, but I think a 4 week ban is a bit much.
Regardless, thanks for your time.
