I contacted Google about this issue in November of 2008 - I only received an automated response. (Matthijs mentioned that was why he posted the previous post[1] on the topic prematurely)

Perhaps with the increasing awareness of this issue, Google will be forced to act.

Why act, they make great effort to explain that the data is public. You can even chose if you want to be indexable (search visibility).
