This. Modding smaller exchanges, I don't look too closely at what people are offering and see if they're gaming unless I have specific reasons to keep a close eye on them, because there are a lot of offers, a lot of defaulters, and a lot of pinch hits. It's just not worth the time. When you're looking at over a thousand participants, oof, there's just no way (unless, again, you know there's something to be concerned about).

And I agree that well-behaved socks aren't a big deal. Behaving well includes actually intending to turn in gifts for each account, though. Agreed with the Al Capone comparison.
