Please send myself or @Brownells a brief description of what you have reviewed, and when you reviewed them. I'm unsure of what happened to all of the reviews since we switched to the new website, but I can assure you that we don't cherry pick. That's evident by the number of negative reviews we have on products at any given time...even the products that bear our own name.
I don't know who places the reviews on the site, or what the criteria are, and I don't even know what priority those are getting right now as we're still working out many of the larger wrinkles of the new platform. The only time that I'm aware of that we remove reviews are when they are factually incorrect, or if the reviewer has been made whole with whatever error there was but didn't update the review.
