Google bases its entire company around automated processes. Sites are made and killed by Google's automated processes every day. If you want to ask Google about it you will be talking to yet another automated process.

this is arash from dropbox. a similar thing happened to us a couple years ago and mattcutts helped resolve it pretty quickly (https://twitter.com/mattcutts). I would try to reach out to him ASAP.
