Academics had begun to publish Scientific Research using the HEXACO model of personality and they HAD discontinued the Big Five model (a.k.a. Big 5, OCEAN or FFI five factor inventory, FFM five factor model) soon. Online dating sites using the Big Five model could be considered obsolete sites, because the Big Five model has been proven as "an incorrect and incomplete model of personality"
------------------------------

eHarmony, is a 14+ years old obsolete site and a HOAX, based on a big scientific fraud, only sustained by big marketing budget.
The Big Five normative test had been proven/revealed as an incomplete and incorrect model to assess/measure personality of persons.
The Big Five normative test had been replaced by HEXACO or Big Six test.
