Do you know if review funneling is black hat? It seems like a great concept. Google, Yelp, InsiderPages, have no way of knowing if a review came from a review funneling site. However, long-term, review sites may find a way to filter positive reviews that came through a funneled site. Am I being paranoid or are my concerns legitimate? Has anyone had success with this method? It seems like a great way to get only positive reviews. I'm just not sure how well this works in the real world and whether it has long-term problems.
