What's the ratio of the former to the latter, and does Reddit have the manpower to tell to the difference on a time frame that keeps the subs alive?
What's the impact of a bunch of people who know how the sausage is made being essentially coup'ed by Reddit? Are they going to shrug and move on? Swear eternal vengeance?
I think it's probably worth splitting this category into two, with one of them being the kind of user who would like to help keep a sub running, but has no idea of what's actually involved or how much time it takes or what a grind it is, and just isn't a good fit for the work involved.
Same way Reddit admins have always done that; by ignoring all but the most egregious violations.
Reddit has replaced mods before. This isn't a new problem, the only novelty here is its scale.
This one is me: I'd love to be a mod in a large community, so I can ban the best contributors randomly and then get them permabanned for questioning me, all so I can destroy the whole thing from within. If Reddit doesn't like the way I moderate, then maybe they should hire employees to be moderators, and set up management staff to oversee them. Of course, that's going to cost a lot of money...
