There is a story about how Google blocked access to a load of documents in their cloud provision because an automated check determined they are in breach of Google’s terms of service. Of course, everyone reads these don’t they (actually they are written in a fairly easy to understand language unlike many, so no excuse really)

But my interest here is how Google (or any such provider) can protect itself given it can automatically check stuff in the cloud. If something got to court I wonder if a judge would request that Google somehow prove that it did not know a given document was illegal, and how it could prove this.
