It's not a long time I'm on Deviant Art, and I've already seen people go, sometimes appreciated fellow artists I was following.
Some were "punished," suspended or banned for their work that violates some of the limits of the site, other just appear as... deactivated. The last one is Peril Investigation. Posting his stories (and writing comments on mine) until some days ago. Then, gone.
Quite distressing, isn't it?
