Fake reviews have been the topic of discussion recently, El Gordo has done great detective work but I believe there is a simpler solution. Based on the concept used by retailers, that of the 'mystery shopper' who evaluate customer service,store layout etc unknown to the shop.
E1 could introduce 'mystery punters' to carry out spot checks incognito. I know.i know it's a bit like binmen,tough job but somebody has to do it.I am happy to volunteer for the Munster area as long as E1 cover all expenses incurred !
