I’ve seen fair amount of this stuff in my career. Just always be careful when reading community reviews on sites like Amazon.com…
With this context in mind, last week we ran across a couple of negative user reviews on Amazon.com that seemed out of character. They seemed especially out of character given that both posters had posted 5-star reviews of Parallels Desktop for Mac, prior to posting less-than flattering reviews of VMware Fusion. After a little investigation via LinkedIn, based on the user names that the reviewers posted under, we found that these reviews were not from actual users but from employees of a competitor, Parallels.
