I don't know about Goblin at all, but on my server we have Linkshells filled with people who still like running dated content, something like Bismarck EX wouldn't be considered dated IMO but do you use Party Finder? that's usually the best place to find people for various things, failing that, post a PF saying you're looking for a Old content LS, I'm sure there will be at least 1 out there.
