Do they still have access to Facebook?

Facebook helps you find friends from your past. But it also brings sadness when you find out that some have passed away. There have been times when I have sent many messages to someone just waiting for a reply only to find out later that they had long ago passed away. At first I wandered how come their page was still up. But then I realized it actually brought comfort to look back at their old post. I have even wrote on their page on days when I am painfully missing them and it helps ease my pain. I imagine that they can still get their Facebook messages in Heaven.
