Yeah, I read that too. Pushing on that topic instead of reviewing is not a smart idea and maybe he came back too soon, instead of waiting a little more and clear things up in his life.
If he's going to come back (and I hope he will, but he has all the rights not to do it), I hope that he'll take really the time he needs, because If I'm not mistaken in his profile he had written that he was still in a weird period of his life; so he'd better think about it rather than writing (even if he said that it is a thing he really enjoys doing).
But more than him, I believe that one bigger problem is some trolls who feel like insulting or saying other senseless things instead of give praise or constructive criticism. (I know that the world is full of those people, no need to remind me that).
Oh, I noticed that he removed his page completely this time...
