They are all the same way, maybe even worse. Google is notoriously allergic to having real people in any step of a workflow, even for paying customers. Twitter is currently going through its own battle with the fact that a huge chunk of the userbase isn't even real. Amazon product quality is going down due to lack of manual quality checking of their sellers. And so on. The culprit is always the same: real people don't scale to the expectations of shareholders, so everything gets automated, and then some very real people show up and exploit the system.
