Seemingly the functionality for setting languages is never used, and a large portion of my new feed is from instances that are language specific (and not the language I speak).

I have set my language to English + Undefined, but it seems no one else can/will set their languages for their posts (leaving them as undefined).

I would like to bulk add these to my blocked instance. I know how to do this.

My question is just - is there a list of instance + language covering the main federated instances?
