Could you at least give credit where credit is due? It's a great disservice to the artist who made these when you post them without his consent, and without acknowledging him. It's not even the case where he asks people money for this, I mean come on!

This is more work from Nyan/Posernyan.

Sadly, and perhaps because of reposting like this, his blog has recently disappeared behind a password/login.

Exactly. He said himself that he closed his blog because his art was posted without his consent outside of Japan. And he closed just a few days after you started posting. So thanks a lot, now he decided that he won't share his art anymore. There was no need of raping his account without his permission, his art was free, it was available in pixiv, in a blog and in a website. You could've posted a few samples and a link, or at least ask him.

I just discovered this and this is awesome. So sad we can't get updates since 2012!
