with css blocked how are you generating such pretty website previews without ignoring the block?

Pay attention, willya? ;) Preview is not a robot and therefore is not bound by robots.txt. It doesn't even look at it. The only way to keep Preview out of css-- or anything else-- is by physically 403'ing it.
