Capricious Gods
Many of these new(ish) tech companies act like capricious gods. You can be struck down at random and never find a human or even a robot to sort things out.
On a smaller scale, there are plenty of forums with discussions where longtime users of Blogger, eBay sellers, Amazon affiliates/marketplace sellers, Google Adsense etc have been barred without notice, any recourse and no-one to take their case up with.
The lesson is - do not rely on any of services as a source of income.
