Of course they could, and one or two is perfectly fine. And if they have other stuff on the dA (like you do) that is more openly considered art, that's fine. It's when they have nothing but selfies, fishing for compliments and absolutely nothing artistic at all, or even saying in the comments or anything that they think it's art.
