No.
What I found with the words you meantiones is this:
http://www.clubkasparov.ru/rev/newsgroups/group02_e.htm
And this is nothing I had said. I did NEVER write something that 75% of the
online players cheated. This is clear forgery by the author there. I did never
say such a think.

As to your theory that I had accused them (team and IBM) of cheating, then you
should quote me in the correct manner. I always wrote and meant that the
non-answering of K's quests was self-betrayal for scientists. Here you find a
clear contradiction to science. In science, they were scientists, results are
worthless, if you lose control of the main variable. The main variable here was
DB2! The machine played chess agsinst K. And we wanted to know how this could
end. But since K was "out of the match>" after the offensive reaction after his
quests the rest of the show event has no more validity. This is so basic. Of
course, from a pure factual standpoint of view, the result is what it is. So, we
will always have the two versions. But I see science in the first place. And
therefore, if I've ever used the combination with the term "cheating" I meant
this in the context of science. Self-betrayal would be a more precise
vocabulary. NB that I always, whenever this came up, pointed out, that this had
nothing to do with the juridical term. That is the same if I wrote "they
violated this or that in science", then this could not be interpreted as if I
had accused them of committing physical, aggressive, brutal violence.

You know this and knew this exactly, Bob, because I wrote it several times. And
we've the interesting fact, that you did never, never, never correct me on this
item of violating the standards and ethics of science. (Ethics, because it's
simply forbidden to offend your client and cause a psycho syndrom OR - and this
is the only case allowed - you wanted to examin exactly the "reactions on
offensive behavior during scientifical experiments".)

The only defense you always used, was the mention that they worked for IBM, they
didn't make science and scientifical experiments. Both is true. And false at the
same time. Because simply it is not possible that scientists suddenly behave
"contra-science", say in sports or other show events. And of course Kasparov was
very certain in his belief that they were scientists who wouldn't do him harm.
Nevertheless the whole question is part of science of science and philosophy.
The main question is "Are scientists allowed to do all what is possible or are
there boundaries?". And we all know the answer. Above science we have certain
basic human rights. Human dignity must not be violated. I for one am very sure
that the press talk of M. Campbell was beyond the allowed boundaries. Because
you can't simply define/ interprete "questions" of a chess player during
tournament, just after a terrible game as offense against a team that didn't
play at all but that was only operating a machine. There is a big psychological
difference. The moment M.C. defined K's quests as out of reasonable boundaries
the whole event was destroyed. I think that this is so simple, so basic and
trivial, if you would try to look at it with neutral intentions. Of course this
is different if you say that even the idea to ask such questions is evil. But
then you would also show a complete lack of psychological understanding for such
sports events. I am very sure that the team of scientists should have reacted in
a different way. They should have talked with Kasparov. Talks to save the show.
Look. If you take the best human player. He has a psyche. If you work on his
psyche instead that the machine alone works on his chess, then it's simply a
different event. It's so basic!

This, only this is why I participated in the discussions about "cheating" etc.
