Well, I can't comment on what ICC was like in the past but I can say
that I have no understanding of the ratings in ICC. I have on more than
one occasion played opponents who were rated at least 200 points above
me and found myself rewarded with 1 (!) extra rating point after beating
them, then I'll beat an opponent rated 50 points less and get 10 points
or more for my efforts, so you can imagine what I think of the validity
of ratings there.

There is a funny possibilty now that I think of it: it is well known
that some players are really very successful against computer opponents.
Even when their colleagues who are rated 200-300 points more than they
do not do nearly so well. This would really mess with the rating system
as let's say a master scores a solid 50% against a 2800 rated computer
account and gains a generous amount of rating points which he promptly
loses to GM X who is only rated 2600 but who outplays him regularly.
This goes beyond the usual nemesis element in which a player due to
stylistic incompatibilities just can't seem to do well against a certain
opponent. In tournaments this happens undoubtedly but on a much smaller
scale (Player A will only encounter Player B about 3-4 times in a year
if that many), but on ICC where tens and hundreds of games are played,
this divergence is multiplied enormously. Perhaps therein lies part of
the explanation.
