I don't quite understand why some artists claim that feedback is not important to them. That they create art for themselves, and don't care what others think. If that were true, why do they post it publicly? Why do they show it to the world if they don't care?
There is a difference between not needing critique, and not needing feedback. Those are not the same thing. All artists need feedback, but not necessarily critique. DA makes quite a distinction between submitting plain feedback, or a critique. People can only submit critique when the artist specifically requests it, which is a good thing. But everyone is free to post feedback. I have met plenty of really good artists who rarely get any attention at DA, which in many cases end up discouraging them to continue. That's how important feedback is to an artist.
I don't know WHY I managed to consistently receive feedback from the community, even when these other artists are way better than me. But I sometimes take the opportunity to invite them to create collab works with me, as means to promote their art. I made over 100 at DA, and sometimes these artists return for a 2nd or 3rd collab just for the fun of it. It's my way to give back something to the community, and perhaps help aspiring artists to get the attention they deserve.
From this experience it seems like, apparently, getting attention from the community does not depend on talent. This might be related to what I said above, about people not commenting anymore these days. Or perhaps the DA community has grown so much (over 4 million artists) that the sheer volume of artists overwhelms people, who can't keep up with all that is produced by the artists they follow. Most likely they've picked too many people to follow, as there is no lack of talent at DA.
Some people claim I got more opportunity because I have joined DA over 10 years ago, when the community wasn't this massive. Who knows? In either case, I nowadays get way less feedback than before, and they are also less meaningful. That's fine with me, because I believe I have learned enough from the feedback I've already got. This is also the reason why I have written that article at DA about the "art of commenting", because I have seen how some people lack sensibility when expressing their opinion, and end up hurting the artists. Most artists are pretty protective about their creations, so people have to keep that in mind when commenting. Of course there are trolls, but at least it's easy to know when we meet one.
Chances are that the moderation process at HW is good because the site is still small. As it grows, maybe more mods have to be hired, or perhaps use unpaid volunteers, and that's where the inconsistencies start to manifest in the form of what appears to be double-standards. It's not done on purpose (hopefully), but instead because different people see things in their own ways, sometimes interpreting the TOS based on their own personal values and beliefs. Happens everywhere, and tends to frustrate the users. The bigger the community, the worse it gets.
For example, in one of the DA groups, a mod has tagged one of my fully dressed characters as "pornographic", because she thought it appears to be sexy. That doesn't violate any TOS, but the mod has the right to claim it does. In her mind, sexy = porn, and there was nothing I could do. It was an illustration of a flying fairy, which many here at HW thought to look rather innocent. The discrepancies in judgement come from the human factor. There is also the fact that not everyone is mature enough perform the mod task. In many cases, DS group founders get desperate to recruit volunteers, and end up empowering people who lack the maturity to wield the responsibility, and these mods end up overdoing it. In any case, it seems inevitable.
