I've been a member of DA for over 7 years. Since that time, I've posted a lot of my work here, exclusively (many of my Linux themes received Daily DAs).
My last big submission was an icon set for the iPhone. I released it free (like I've historically done with my themes). Things turned out bad quickly. Some kid jacked it, and turned it into an icon set for Android devices. As if that wasn't bad enough, he removed any mention of me in his "release." The groups that featured his set picked it up and gave it traction. Most I contacted were cool, pulling it and labeled him an "art thief." A few scoffed at my claim of ownership and left it regardless.
Before the dust settled, I also reported his entry to the DA powers that be. To this day, I never heard from them. In fact, I don't know a single sole that has.
Since that time, I've been working on a successor to my original set, expanding on it greatly. Now that it's complete, I am wondering if I should even feature it here. From my experience, DA doesn't seem to support it's artists, or care much about art theft. They pay lip service to it, but that's about all they do.
So after 7 years, here we stand. At the precipice and my finger hovering over the "delete account" button. To be honest, I no longer enjoy this place. There are tons of talented artists, but the ads, the aggressive marking "notices" DA sends me almost daily, and of course the lack of action when it comes time to protect your long time supporters, has all taken a lot of the magic out of this place. I used to value my account. But now, it seems that anything I post is ripped from me, slapped over some half-naked chick (by guys who call themselves designers) and I'm lucky to even get a link back. With places like Dribbble and Behance, I'm wondering why I should even stick around and promote this place if the guys that run it don't even stand behind the people that built it for them?
