Take https://lemm.ee/c/moviesandtv for example. From lemmy.ml, lemmy.world, and sh.itjust.works, you can’t see any posts or comments from lemm.ee users, and lemm.ee users can’t see any posts from other instances.
I don’t know what’s broken, but something is badly broken.
Another thing I’ve noticed is that I can’t post pictures on lemm.ee at all, no profile picture, post, or comment picture.
I think thats on purpose. Storing images is heavy. And besides, theres plenty of image websites.
So how do you do profile pic hosted elsewhere?
You don’t.
They blocked it because of lemmy shitpost community incident
