As far as I can tell it is common on Reddit for manual review of automated mod actions to just not happen. If it does happen, it’s often irrelevant anyway when it’s a day or two later and everyone has already moved on. I can’t really give numbers or evidence and this is only based on a handful of inconclusive anecdotal experiences, because Reddit moderation is deliberately opaque. Given that, people should probably be wondering what they’re trying to hide.
