They aren't verifying identity, they are verifying skin color and using the information to then discriminate against their users. A person with verified skin tone and not verified identity can dress themselves in all sorts of lies just as trolls do everywhere on the internet.
>How do you think it feels to be a Black member of a forum and see a White person who is taken in by a White troll pretending to be Black? Conversely, how do you think it feels to be Black and be arguing with someone White who is sure you are a White troll pretending to be Black?
Maybe we should focus on ideas over identity.
I'm not saying it's a good solution in an absolute sense, nor do I have any idea how well it's working.
I'm just saying I think it's obviously motivated by a real and inescapable issue, and I don't think there is a simple and obviously better solution given the constraint that you want to have an online forum where people can acknowledge and discuss things related to racial identity.
Anywhere race is a topic and anyone can join, but there is no verification of identity, trolls can claim anything. How do you think it feels to be a Black member of a forum and see a White person who is taken in by a White troll pretending to be Black? Conversely, how do you think it feels to be Black and be arguing with someone White who is sure you are a White troll pretending to be Black?
It's not a trivial problem, and it's inherent anywhere your online identity isn't linked to your real one.
