Take this post, for instance:
https://fedia.io/m/lemmyworld@lemmy.world/t/6403/Does-lemmy-world-allow-criticism-of-the-CCP
The user and magazine are both from Lemmy.world, but next to the title it says (fedia.io). What does that site in the parentheses mean?
Surprised no one has linked this Tampermonkey script that was just posted to Fedia: post.
Among other things it adds “@domain.com” to any links that don’t have them. It maybe doesn’t directly address the confusion, but it should help :)
