In the Arnold biography True Myths, author Nigel Andrews talks to
Lacey H. Rich Jr, who runs the opposite of a fan club ? a fiend club?
He does this to get back at Arnold for winning the 1980 Mr Olympia,
which he thinks should have gone to his friend Mike Mentzer.

I want to know if this guy is still running his non-fan club, and what
he?s been up to. Please note I am not asking for any details of his
personal life.

Markabe, 

I am not posting it as an answer - since I could not find where he is
today. There is virtually no online presence of him online since 1995.
In 1995, he published parts of chapters of his book about Arnold on
the Usenet. He also referred, on that occasion, to the question: "Who
is Lacy H. Rich Jr."?

What Google dug, of his Usenet posts, could be located here:

Before that, in 1992, he was the source of a Spy Magazine exposé about
Arnold's behavior. See:

(a porting titled "Arnold Schwarzenekkid!").

And that's it: I couldn't locate any activity after 1995. There are
few 2003 (election) posts - but they refer to his previous activities
and in no place is he actually quoted.
