wikifx is fake website that collected companies from all over the internet, they are in partnerships with some shady forex brokers, whome they promote, other brokers names they use for SEO, those who are not their partners they gave these companies low rating and fake reviews, also they post fake articles about these companies. Then they contact you and offer you their "services" which means they ask you to pay them money in order for them to remove fake materials about your company which they made up themselves in order to blackmail you. I saw a lot of such complaints, and I also work in such a company who received a money scam exmail from wikifx.
