Some people whom I trust indeed said it is him. 

He seems to be interested in quite esoteric subjects so I’m not really keeping tabs on him 🤔

I linked to the website in the post, which is identified as his, but I have not seen that profile.

Wei Dai Ignore This Guy?

There's a [twitter account](https://twitter.com/weidai11) that claims to be him. Created in 2015, It was mostly inactive until late November 2023. 

The bio links to [this website](http://www.weidai.com/) and to [this profile](https://www.lesswrong.com/users/wei-dai) on Less Wrong. 

Seems like it could be his.
