Bloggers Who Lie
This happens in the beauty industry every single day. They call themselves 'beauty bloggers', and while there are a few honest ones out there, there's FAR more who desire the money from the cosmetic companies they are supposed to be reviewing. This makes it pretty difficult if not near impossible to find honest opinions about a product or service. There are even surgeons and other practitioners who will offer free services in exchange for a positive review - so often that sometimes beauty bloggers are boasting about how great something is before they've ever received it or tried it.
