I am not. You should re-read my point. Whether their review was rejected or not didn't stop them from spending $50k on amazon. They are as replaceable as warehouse workers.
The $50k thing has nothing to do with status, it has to do with amazon already possessing a very good signal as to whether or not this account is "real".
It is potentially interesting in the context of whether or not amazon is in fact serious about improving SNR in their review system.
I am just saying Amazon has no reason to differentiate between real people or bot people if the OP continued to buy from them despite their critical reviews being rejected. Amazon doesn't care about their past purchase history as long as they buy more from them in future. Whether they spent 50k or not didn't make a differentiating factor for Amazon.
Again, the goal isn't to "stop bots from buying", but rather to stop them from posting fake reviews. You're reframing the whole discussion to something that has zero relevance to the discussion.
