Tbh I think the display names as they currently work are dangerous. What would prevent me from setting my display name to nutomic@lemmy.ml? Most front-ends would not show that I’m actually not you at first glance.

Edit: Misread the question as being about display names. Full unicode support for usernames would be even more dangerous, basically opening the door to unicode homograph spoofing on that level too.

I’d advise against doing any mod actions from a non-local account until v0.18 is released due to this bug in previous versions: https://github.com/LemmyNet/lemmy/issues/3075

TL;DR: Any change to a community by a non-local mod makes it “homeless”, breaking federation.

I was thinking of something like that too, but probably never would’ve gotten around to implement it myself, so thanks! Could you put your script on Github or something maybe?

Also it would be great if it could copy at least top-level comments by OP, because that’s often used for linking to a source.

They are separate. Think of community names like email addresses: john.smith@here.edu is different from john.smith@there.com

Similarly, gaming@lemmy.ml is different from gaming@beehaw.org

I’m commenting here from another instance (feddit.de) where I’m logged in and this community is available at https://feddit.de/c/lemmyworld@lemmy.world

Similarly, you can just access communities from other instances here, e.g. https://lemmy.world/c/asklemmy@lemmy.ml
