I'd be surprised if you receive an answer. I'm one of the original forum members (1995) and over the years I've had many posts deleted; never been given a reason why for any of them.
Any post I make in Rumours and News seems to be deleted shortly afterwards; I've never understood why. However, I suspect a particular moderator there has some sort of childish grudge against me, dating back to the time before he became a moderator. Anyway, I just let these things pass me by, life's too short to worry about it.
