USA Fraud Agency Call On Dating Industry To Improve Fight Against Scammers (via GDI)
The Online Dating Industry is selling elixirs, tonics, snake oil liniments and other patent medicine and performing like the Pharmaceutical and Cosmetic Industry before the USA Food and Drug Administration was created where any player can make any claim without any credentials. I live in a South American country and I am really astonished to see how online daters in "1st World" countries are really victims of human experimentation. No actual online dating site is "scientifically proven" because no one can prove its matching algorithm can match prospective partners who will have more stable and satisfying relationships -and very low divorce rates- than couples matched by chance, astrological destiny, personal preferences, searching on one's own, or other technique as the control group in a peer reviewed Scientific Paper for the majority (over 90%) of its members.
