Youtuber Taylor R. answers ONTD regarding this post.
In the video she addresses the claims that allegedly her husband was the owner of a sketchy website that contained adult content, underage girls and prostitution.
Long story short: she says that everything is false and someone is trying to hurt her by hurting her husband.
Edit: I personally watch her videos and I believe what she says about not being involved in prostitution on this website or ever. I believe her about her experience.
She could've just ignored all the claims and keep living her (rich) life, but she explained everything well, although I'd love if someone who speaks cantonese can confirm what she's saying is true.
