As of March 18, Mercado Livre (a.k.a. Mercado Libre in Spanish) has prohibited ads of used cryptocurrency and prepaid game products on its Web page. If users didn't obey the policy, Mercado Livre spontaneously removed the advertisements from its site on March 19. However, users can a create a new ad as a new product. Mercado Livre has surpassed Amazon in Latin America. Paypal invested $750 million in Mercado Livre. The rationale behind this investment is that Mercado Livre is a continuous key player in the growth of D-commerce in Latin America. For more than two decades, Marcos Galperin along with his firm have made a strong investment in fintech and ecommerce in Latin America. Marcos Galperin is president and CEO of Mercado Livre. Major tech companies (i.e. Facebook and Google) have launched similar prohibitions in the past. In June 2018, Google banned all cryptocurrency ads due to a new change in their Financial Services policy. As a result, companies couldn't serve cryptocurrency ads on Google's own websites and sites from third parties in its network. After Google's cryptocurrency ad ban, crypto advertisers noticed fewer views of their advertisements. The new policy also banned ads about ICOs, crypto exchanges, crypto wallets, and crypto trading advice. Unlike Facebook, Google is not clear about the future of cryptocurrencies. It has not seen the harmful effects of cryptocurrency on consumers. Google (Alphabet Inc.) supposedly put keywords referring to Ethereum (ETH) on a blacklist on its marketing platform, Google Ads,in January 2019. The search engine giant presumably mentioned that crypto exchanges aimed at the U.S. and Japan could be promoted on the site, and that picking different nations could be the cause for advertisement denial. Developers who were performing audits on smart contract securities saw an error alert when using "ethereum development services" and "ethereum audit securities" as keywords. Nevertheless, keywords referencing EOS showed ads. Facebook disallowed advertisements using deceiving marketing practices, including cryptocurrency and initial currency offering (ICO) ads. Therefore, scammers will have a hard time profiting from their ads on the platform. Also, Chinese social media networks have forbidden cryptocurrency ads.
