Good question. I have wondered that too. I have also wondered if any former players do. I asked Duhon if he did when we went on that golf trip, and he said he does not. He gave me the impression that he also doesn't read it.
I've wondered if any former Duke players post as well. On premium site there's a guy with avatar Tate Armstrong. He's very respected by the others, and catches no criticism or disagreement from anyone either, and he's only been posting on DI since 2016.
