The artist left because an anonymous hacker managed to take away his twitter account. Apparently he had been dealing with depression and because of this, it set him off to becoming more sad. Do not just excuse someone's reaction as unnecessary drama when there is more going on in that person's life that's giving him bad faith. If anything, it's us who owe this artist for the erotica he drew. So next time, don't just jump the gun and demean him for needing to take a break from the internet to deal with other issues going on.
