We normally don't allow very specific URLs like this, but we'll make an exception in this case. It's interesting, valuable information and does not reveal any personal information as far as I can see.

googleusercontent.com is a domain owned by Google, Inc. It is used for content storage by Google Plus and other similar Google Services. It is a content delivery network.
