So I made a similar comment to this on User:SOTO's talk page, but I know how busy admins can be, and it's a more general question than a "this needs to get done immediately" sort of thing. User:DiSoRiEnTeD1 pointed out that on Rose Tyler there was some "random letterings" - ie, a dead link to the Korean Wiki, which has closed down. Since then I've noticed similar things in a few other places, like Clara Oswald and Doctor Who. Is there a general policy to handle foreign wiki closures? Should I just not touch stuff in case it starts back up? Should I remove the dead links wherever I see them? I'm unsure what to do, and it's a bit frustrating.
