Maybe some kind souls with more knowledge in the anime world can help. Just want to generally know about nyaa

First, is this the site:
https://nyaa.si

Or is it this one, which says they are "going underground" and want user to download and install a "binary client", says other sites claiming to be nyaa are fake. "Binary client" does not sound cool to me.
https://www.nyaa.eu

nyaa.si has a lot of torrents accessible without registering, and I wonder if more are available to members?

Some older discussions talk about nyaa being open but it's currently closed to registrations. Wondering if it's worth the effort to become a member?

Nyaa.si is the real site. You don't need to register. Everything is accessible without. Registration only to comment.

Thanks @redsheep
