maybe put “This is what it took to defederate from exploding-heads after being federated with them since the start of lemmy.world” before the screenshot of the post, as right now it seems confusing.

🧟John is a 🍎lemm.app user, he subscribes to 🐢turtle community on 🍌lemm.ban

he is the first ever to do this on 🍎lemm.app

so 🍎lemm.app creates a copy with the last 20 posts and now will always keep in sync with future posts

👩‍🚀Jill is also a user on🍎 lemm.app, she subscribes to the same 🐢turtle community but a year later.

she will be able to see all the posts of that year all the way up to those 20 posts.
