For now, it's just removing AutoModerators and things labeled as bots. Now that I'm reading this again, I realize doesn't really help, since bots pretending to be people recommending products, don't get filtered out.
That strikes me as very naive. Reddit bots are never marked as bots, that's the whole point of astroturfing. Youtubers aren't diligent about disclosing sponsorships either, regardless of what their ToS say.
I think this is a very good point. We've focused a lot on correctly matching reviews with products / brands, but haven't taken hard enough of a look at astroturfing.
