Where did the post go?

I just look through the “Live broadcast” and see this post:

Became interesting. I click on it - "Page not found." I click on the user, I look at his messages - nothing like that.

Now the question is: where did the post go? If he had been preoccupied, he would still be available, right? So the author hid it? What for?
