I shoot 36Mp D800 RAW images in ISO100 with tripod and use high quality prime lenses. I also suffered from "out of focus" rejections for my tack sharp still images. Now I downsample to 12Mp and "out of focus" rejections are minimal as well as noise rejections. So, you will reduce "Noise" rejections as well by downsampling...
Thanks for posting this. I'm glad I'm not the only one 
I also shoot with a tripod with prime Nikkor lenses and even use a infrared remote AND stacking focus software occasionally too 
It's complete madness. I belief the current situation with SS reviewers is nothing short of ridiculous.
I forgot to mention that I shoot all my photos with mirror up and shutter release delay in D800 to prevent vibration. My prime lens I mostly use is Nikon PC-E lens which allow me to shoot sharper images by tilting with wider aperture to prevent softness due to diffraction. All the RAW images processed in CaptureOne pro and reviewed in Photoshop at 200% on 24" IPS monitor.
As understood, I did my part for a sharp image by spending a lot of time on each image and I don't want to spend more to prove my images by sending tickets, mails etc. So, SS please solve the problems with the reviewers.
