Can anyone recommend a good article or video explaining how ActivityPub works on a technical level? I understand the concept, but I’m interested how the protocol actually works (I am studying CS for context).

Activitypub uses ordinary web protocols like https to make requests between servers. It’s all quite simple.
This document is quite detailed: https://www.w3.org/TR/activitypub/
Thanks, it is indeed quite simple. I guess the part that confused me was how lemmy communities are modeled. Apparently, they are just actors of type group and submitting a post is simply sending an activity to the group and its followers. So, the email comparison makes sense after all.
