My niece does p*rn and her dad / my cousin follows her

I just want to clarify that my niece is of age and she’s older than me, I’m 18 and my cousin is 40 years older than me. Also in my culture we don’t do the first cousin twice removed so that is why she is my niece and not my 2nd cousin removed. I follow my cousin on social media, he made a post about his wedding anniversary and he listed his kids names. I’m only in talking with the youngest, tbh my cousin isn’t close with his family simply because he thinks he’s better than everyone. So yeah I search up his daughters name in his following and lo and behold he is following her p\\\*rnstar account. I don’t know how to feel about this. I don’t know if I’m more ashamed of her for pursuing it or him for following his daughter’s account. I don’t think he watches it, and I bloody hope not, but what father supports his daughter doing p\\\*rn?
