taken from rule34 directly beyond your question there:
Violetty: @tyciol: He's taking a break, he said he wanted to take a step back from art. Hiatus it seems. I sure hope he's doing well
and my personal opinion why his 3 accounts have been closed: the reason could be because many accounts from diferent artists got hacked. even while they were absent. and because he could know that, he closed all of his 3 accounts to make sure nothing happens while he is absent.
