There 2 FREE online dating sites (1.0 only search engines) getting some traction here, in some Latin American countries (Venezuela, Perú, México, Colombia, Chile and Argentina but NOT Brazil). The Spanish translation is excellent.
They share their databases, OasisActive and AmorEnLinea, both owned by the Australian 3H Group (the former owners of Match).
Those sites are 100% free, ads supported only.
3h Group also owns TataDate for the Chinese market.
It is quite intriguing, they are full of profiles of old persons (over 60 years old)
Those profiles seem to be REAL.
Here some screenshots:
