Why is published in a personal blog post became a draft?

A couple of hours ago I published a post on his personal blog about your analog VkOMG(a convenient way to make myself a combo avatar). Post touched Vkontakte, and of course, I immediately prepared for the worst. Fears came true, karma and post of course zaminusovali, but it's not terribly surprising that the post became available and moved into drafts. I looked in the "help" section but nothing there is not found besides that, you can publish a post in a personal blog with karma >= 5 (I was 5 at the time of publication).
Now post a -6 rating, this is enough to post is gone in the draft? If Yes, then what is the threshold rating at which a post becomes unavailable?
