South American sites had failed.

Free, Ads supported sites, are not viable (OasisActive, AmorEnLinea, DatingArgentina, DatingChile) because free online dating sites perform only as marketing tools to send free users to paid online dating sites and convert them in paid ones. To be profitable, they need the commissions paid by those paid online dating sites: That is the only way sites like PlentyOfFish and OkCupid can be profitable, and in South American countries paid sites had also failed (ZonaCitas, TeBusco, ParPerfeito, Match, eHarmonyBrazil).
