With the number of Review sites popping up left and right as well as video/dvd review sites, has it become harder to gain access to this content for review?

At one time you could get a video/DVD screener for review with little to no resume and I assume the same for site review but in today’s markets is a resume or credibility list standard requirement? And if not, what's to stop a surfer from getting access based on a simple request?

I ask this because of BDBionic’s plagiarism thread. Would the trend of review sites cause people to steal text because they cannot get access to the sites themselves? (As well as being lazy and looking to fill a site with reviews)
