D800 @ B&H : Better Quality or Review Censorship

I noticed that almost all of the 170+ reviews for D800 on B&H are positive with no mention of any left AF issues.

Here is Amazon for comparison

I wonder if

1. B&H does some QC checks before shipping the cameras
or
2. Nikon does this before shipping to B&H as they are a big camera store.
or
3. B&H censors negative reviews or comments about the left AF issue.

Anyone here leave a negative review that did not make the site? I ask because my review of a Nikon 50mm 1.8G lens I posted 2 months ago was censored.
