Your thread was not an idea or anything, it was complaining, which can be considered spam. Opinions are fine, just keep it to yourself. Everyone else seems to enjoy the deco layer.
You know what: I like the deco layer. I understand it takes some of the challenge away from pixel art, but it replaces the shortcomings with better looking artwork. Personally, I prefer to not use it, as I think it is cheating a bit, but maybe it is worth it. Just look at the quality of art. Now, people are no longer bound by the elements available; their only limit is their imagination. And I am on the mods side. If you voice your opinion in a carefully structured manner, then they will be understanding. You may see an argument, but all the mods see is a raging user. It helps to take a moment, think your arguments through, maybe even numbering them, and assertively, but not aggressively put your opinions and ideas forward.
I didn't lock the first thread so you would go and make a second one. :P Opinions are fine but we're not about to remove the deco layer just because it breaks creativity superficially.
