It'd be great if someone collated the data for the reviews and pointed out which companies tend to have the most "fake" reviews. It'd be a bit difficult to do so, but I can think of at least a few ways to try (date and frequency of reviews, "corporate speak," median length of reviews, distribution of "stars", distribution "helpfulness", writing style analysis, etc.)
