In what country hasn't the legal system caught up?

The point I raise is that the internet is international. There are N legal systems that are going to deal with this. And in 99% of them this isn't going to end well for Google if plaintiff can show there are damages to a reasonable degree.

It's bonkers in terms of risk management.

If you want to make this a workable system you have to make it very clear this isn't necessarily dangerous at all, or criminal. And that a third party list was used, in part, to flag it. And even then you're impeding visitors to a website with warnings without any evidence that there is in fact something wrong.

If this happens to a political party hosting blogs, it's hunting season.
