@innocentzero@social.tchncs.de @ricci@discuss.systems @jaredwhite@indieweb.social In the ActivityPub world (and also the Nomad/Zot world), the posts by all users from other instances that you follow are pushed to your instance. In other words, those posts are stored on your own instance. Suppose, for example, you start following me. Then your instance will pull in every post I make. If your instance exposes the public global feed, then a visitor can browse through my posts on your instance. They can search for specific posts by me there. If I post something that’s illegal in your jurisdiction, then since that post will be publicly visible on your instance, you (as the owner) are liable.
