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.
Make the support request cost $250-$500. Guarantee a human on the other end. That drops spam/scam attempts down to basically nothing. It also helps cover the cost of providing real review. Plus, $500 is a very reasonable expense for most companies (basically negligible for all but the smallest), and it's a high bar for scams/spam.
Basically - No, your answer is not a valid reason to not provide human based support.
