Individuals can freely “discriminate” on dating sites as they desire. They might not want to see people of other races, religions, sexual orientations, or to be seen by them… that’s their choice. As well as people over or under a certain age or height or even income; eye or hair color, occupation, political leaning, wants kids, had dogs or cats, etc. Thus I suggest they create a comprehensive dashboard for each user to make their own choices about not just who they wish to see, but also who can see them.
Site-wide it’s a very slippery slope. If someone doesn’t say outright they are interested in, say, Jewish people, should the site go ahead and make the assumption and block Jewish people from even being able to find them? What do you think the response from Jewish people would be, to find out that they are BLOCKED from using the site’s search function in ways that other people aren’t?
For age, many answer the question “Would you date someone twice your age?” as either “yes” or “age is just a number,” despite whatever preference they’ve stated. So this is only a “preference,” not a “mandatory.” If you’re 51, you cannot search people whose preference stops at 50.
Since this, they’ve gone even further and have adjusted the matching algorithm to include age preference. If you’re not in their age range, you lose 10 percentage points automatically. This, where most have accepted the algorithm as relating to “personality match.” This is also discriminatory. Users can see the age right there and make a decision without OKC “helping” by disparaging other users’ score.
The older you become, the less functionality you have on OKCupid, in addition to now being basically disparaged. That is ageist, and is outright discrimination.
