SnackExchange is a pretty light-touch subreddit. "Problem people" are a rarity here; the anti-scammer bot does an incredibly good job of keeping would-be scammers out, and you'll find that cases of fraud/scam, while they do ever happen, are extremely rare. As such, I genuinely envision myself needing to do very little. I'm always nervous to use the "nah this community just runs itself!" phrasing, but.... it really does come pretty close.
I really hope they leave with their bots, just to spite him. Too bad they won’t though, some mods are fools who care far too much about communities that couldn’t care less about them.
