I've heard it said that many so-called "exit counselors" do just as much harm as good. Some have gone so far as to abduct the alleged "cult" member forcibly and practically brainwash them in order to de-brainwash them. Many are on an anti-cult vendetta that is, itself, rather cult-like.
I don't see an "exit counselor" doing much good to a JW wavering in the faith. I certainly don't seem them doing any good to a JW that doesn't want to leave the fold.

PS...the so-called WHY-1914 "helpline" can do some good, but is unquestionably from a born-again Christian perspective. When I left the JWs about three years ago I called the "helpline" and talked to a couple nice, but highly evangelical, folks who offered some good advice. One woman -- not Marilyn -- told me that she believes in modern-day miracles and said that she knows a pastor who raised someone from the dead. I'm not kidding. It was very "Twilight-zone-ish" and, if I didn't know any better, felt that the woman wasn't playing with a full deck.
