It was written 2 years ago; now my answer to that post is: please read the paper "The HEXACO Honesty-Humility, Agreeableness, and Emotionality Factors A Review of Research and Theory"

Recent evidence from lexical studies of personality structure confirms that a common set of six—and not more than six—dimensions is recovered across diverse languages. The HEXACO model of personality structure is based on these six lexical dimensions, and operationalizations of the HEXACO factors correspond closely to the lexical factors.
Given that lexical research forms the ultimate basis of the Big Five and even of the FFM, the finding of six rather than only five replicable dimensions suggests that the widespread adoption of five-dimensional personality models was premature.

As Ashton and Lee (2007) demonstrated, the HEXACO factors of Emotionality and Agreeableness are not identical to the similarly named factors in the Big Five model. Specifically, HEXACO Agreeableness hypothetically shows positive correlations with Emotional Stability and Agreeableness of the Big Five, and HEXACO Emotionality is expected to show a negative correlation with Emotional Stability and a positive correlation with Agreeableness of the Big Five (Ashton & Lee, 2007).

Please remember:
Academics began to publish Scientific Research using the HEXACO model of personality and they plan to discontinue the Big 5 model (a.k.a. Big Five or FFI five factor inventory) soon; because Big Five normative test had been proven/revealed as an incomplete and incorrect model to assess/measure personality of persons. 
I think, legally, online dating sites using the Big Five model of personality could be considered a FRAUD because they are using an incomplete model of personality. They are assessing 5 scales and not 6 scales.
