I think it theoretically can’t be done. The protocol allows anyone to query for posts, and it has to work that way unless you want to move ActivityPub federation to an invite-only system. On most servers I think browsing while being logged out is sufficient, just like on pre-Musk Twitter.
Unfortunately not. For me the main problem is discoverability. There’s no recommendation algorithm except for boosts. I’m not suggesting Mastodon integrate some kind of machine learning or other advanced stuff, but number of likes from followed accounts and a threshold would be nice for a start. As it is, Mastodon is just bad for entertainment purposes. Maybe it works for other purposes, but for entertainment I’d rather have the algorithm-fuelled quote-tweet dunking on Twitter.
Reminds me of the funghi in Chernobyl that photosynthesise nuclear radiation.
