And the mods are the ones that fight the phishing scams, disinformation bots, t-shirt spammers, etc. If reddit were capable of automating those away, they wouldn't still be so prevalent.
I straight up don't believe reddit staff is as technically competent as those at Meta/IG or TikTok. They can't pull it off without a volunteer army filling in the capabilities gap.
I'm more inclined to believe it's just incompetence.
