What thing is consent? Mastodon is an odd sort of network, there's more blocking than I expected and it somehow seems as if blocking is an intrinsic part of the design. In Mastodon, blocking looks like a choice one makes for whatever reasons, not an unloved measure needed for fighting abuse. As if the design doesn't tell users "you can follow people in the fediverse" but rather "your ability to follow people in the fediverse is limited by you and three other parties and the software isn't among the three". So… if the mastodonish idea of consent doesn't extend to all of the fediverse, what makes bluesky different from some unvetted mastodon site run by weird people? If the poster's/follower's/would-be follower's consent isn't taken for granted in one case and isn't taken for granted in the other, what makes the two cases different? There obviously is a technical difference, but what is the difference wrt. consent?
