> There's no chance I'm going to vouch for something other people have flagged: I'd never have enough certainty that I'm more right than they are, not enough to risk your retribution. I value my ability to participate in this community too much to help moderate it under threat of punishment for doing so poorly.

This is confusing to me. Unless there's something nobody told me (always possible!) the only "punishment" they'd institute would be removing your vouching privileges. Not making use of the vouch feature out of fear you won't be able to use that feature seems entirely paradoxical. It's similarly paradoxical to say "I value my ability to participate too much to actually participate" unless I've simply missed some part where they say "we'll take away your submitting/commenting ability."
