How about every time ALL of these conditions are met:

1. 1000 "Yes" responses...
2. From 1000 different IP addresses.
3. Each "Yes" response was at least 150 seconds after the page request (Anonymous user must read and comprehend the post).
4. "Yes" to "No" ratio is at least 3 to 1.

Then the user (post author) gets a "Goodwill Ambassador" badge.

On the flip side, for "No" responses? Maybe a "Raspberry" badge?
