What tools will those new moderators use? The mods of any decent size subreddit have to use third party tools because the first party ones are apparently garbage.

I think a better question is what's Reddit's endgame? Mods of huge subreddits will just capitulate and use Reddit's crappy tools to do their unpaid work? Somehow those subreddits won't be flooded with spam and trolls? People will stick around to look at ads when every other post on /r/awwww is gore because the mods won't be able to keep up? Everyone will just download the complete shit that is the official Reddit app?
