There are users who zip through the review queues with an incredible fast speed, look for example at these time stamps:
Doing 3 review in 16 seconds, one of them in only 3 seconds? This leaves hardly time to load the page, let alone to actually read the post.
Can some minimum time for reviews be added to avoid robo-reviews? Maybe allow reviews only every 5 or 10 seconds to increase the probability that the reviewer is actually reading the post?
