For more than fifteen years this debate has raged on. Countless hours have been spent in any manner of editing program you can think of to bring these items to the game. What takes one artist a week will take another ten minutes, and there is no objective standard by which to judge the worth of either.
Graal wants to call itself the owner of anything you upload. Graal doesn't know the first thing about copyright. Pixel edits are a way of Graal and have not been moderated or really thought about in a constructive way, well, ever.
It's a crime to steal money from people, no matter what their graphic is. Some of your favorite graal images come from my server, and we recognized early on that people are going to take things and edit them and that's beautiful.
I hope you get a refund, OP.
