But Google (and Facebook, and probably some other companies) don't have reasonable processes for disputing or resolving these situations.
Some have said that we should consider Google's challenge: lots of users/activities that need to be monitored and policed. The assumption is that Google could not afford to do this "reasonably" with humans instead of automated systems because the volume is high.
But Google certainly could hire and train humans to follow a process for reviewing and assisting in resolving these cases. They don't. It is doubtful that they cannot afford to do this; I haven't checked their annual report lately, but I'm guessing they still have a healthy profit.
In the unlikely event that involving more humans would be too expensive, then Google should raise their prices (or stop giving so much away for free).
To summarize, there is no excuse for Google to operate this way. They do because they can, and because the damage still falls into the "acceptable losses" column.
They'd waste 99% of their time with spammers, scammers, and attackers trying to social engineer account access. There's no reason to waste a human's time on that.
Google is already wasting 'a human's time' - but its the user. When a user is banned, an enormous amount of time is wasted trying to re-register their new email with every single website, service, bank, etc - at times talking to a human to fix things. And that is the best case. The worst case is that their livelihood is affected - app developer, youtuber, etc.
The status-quo needs to change - and Google should provide better service. It doesn't really matter if they hire more humans or not.
