Review spam filter

- ESFiltro antispam de reseñas

Google's automated systems that check every review, before and after it's posted, and block or remove those that look fake or break its policies.
E.g.A new San Diego restaurant gets 25 five-star reviews in two days, mostly from brand-new accounts: some of them never show up, blocked by the filter.
