At the restaurant we're besieged with sales calls.
The latest a scam to "improve" your online reviews - reputation management, as it were, the theory being that if you pay this company money they'll improve your restaurants/business reviews by posting loads of bogus reviews that rave about the service, or - as has been done in the US, simply by logging in and deleting negative reviews, because coincidentally they happen to own the reviewing websites.
Now this completely undermines the "fairness" inherit in the process of reviewing restaurants, and destroys whatever use the internet might have had in helping customers decide where they would like to dine. Never mind that, in this instance it's not about the customers, it's about the reviews (and one has to wonder then if these companies don't perhaps stoop to posting negative reviews themselves, just so that they can remove them later for a fee....).
In short, it's a fucking scam of the worst order.
