Be fairly afraid. Here's another relatively well known person getting caught up in Google's T&Cs despite having done nothing wrong.

I've no way of knowing what has caused these problems. It could be an innocent mistake, an internal or external party with a vendetta, something I've done... But there's no way for me to find out. Google doesn't do customer services - that's part of its business plan. Got a problem? Feel free to kindly piss right off.

That's no way to live. Constantly in fear that one day the most powerful information gatekeeper on the planet can decide you are persona non grata.

It's time to start moving away from Google. I know it won't be easy, but it's now obvious it is the right thing to do. If I'd been away on holiday, or couldn't afford ID, or wasn't acquainted with several Google employees - this could have been an absolute disaster.
