Looks like he was hacked according his Patreon: https://www.patreon.com/njwildberger

I hope he'll recover. He really makes math fun and interesting.

How can this happen? Did they get hold of his email

Oh man. That sucks. I really enjoy his content. I've been going through his "History of Mathematics" series lately. Great stuff. Hopefully he's able to get all the content restored.

He pulled the root, I guess..
