This was my point basically, they don't care about whether a player is a winning player or not, but any high volume player is surely, by definition, a winning player, otherwise they wouldn't be playing very long so as to enable them to continue to contribute to the rake.
And as I said I think they are trying to protect their bread and butter, and trying to re-create the image again that it's a friendly environment to play poker safely, without worrying about having their money stolen by a rogue site, or to be the target of a card shark.
