are you saying that if a site is entirely hosted on TOR then no information makes it to an endpoint?

Basically yeah. My understanding is that exit nodes are special and using them is a vulnerability, but you only use exit nodes to access clearnet sites from Tor, and you are less vulnerable if you aren't doing that and rather going to sites with .onion urls. Which, unfortunately I can't find one for this website, but I'm thinking they'd probably consider making one if they can't maintain any clearnet domains anymore.
