Steward Badge gaming visible in the Review Close Queue
I've noticed that most people who /Review a lot of close votes on ServerFault do about 12-20 reviews a day. That seems like a reasonable number, it means they've cast a few votes while reading questions, then the rest when /Reviewing.
But there are a few people who are regularly doing 30+ or 40+ reviews per day (I think the most I've seen is ~50). That means a lot of their reviews are "Do Not Close," and I think some of those are iffy, i.e. questions with a couple downvotes and 4 other people voted to close but a "Do Not Close" from one of the accounts I'm wondering about.
Obviously, some Do Not Close votes are to be expected - people have different opinions. Since Data.SE is still not updated, I don't think there's any way to get accurate stats, and although I think I see a trend when browsing through my list of reviewed questions, I know that's pretty subjective.
But it got me wondering if there's any problem with people egregiously voting "Do Not Close" and if the system does anything to track /Review behaviour. I'd think that in an extreme case, (someone who blindly picks "Do Not Close" for everything), it'd be good to exclude them from reviewing.
