You're certainly not going to get him to put in appearance if you are horrid to him.
Perhaps it'd be helpful if instead we posted nice "Where are you, how are you?" messages... someone could pm him again or even do that thing where you see where they've been or when they last logged on, I haven't time.
On the other hand, it might be possible that a certain mod or two, to whom he's been very real and fun(ny), has deleted every last message he's posted recently?
Could be he's gone on holiday and doesn't give a flying f**k about Getbig these days.

He'll be back. Either that or he's still here, but under another name.
