They do nothing whatsoever when an obviously false positive review is reported to them. "what we can not do is challenge the authenticity of a review based solely on its content". I mean, they blind themselves to a pattern of blatantly false reviews by staff of a company that is not delivering. So I have no idea why they have a 'report' button. Their reviews are therefore not trustworthy and their compliance superficial and easily circumvented. Just LOOK at the House Simple reviews - its SO clearly written by that company's staff...even a 6 yr old would spot it!!! Devalues everything the do and so will never reference them again.
