Include the obvious ones. I've got them already probably but who knows what I might have missed.
Include banned subs too they're still accessible.

Good chance that I fail to rescue ani_communism as it's not in the top 20,000 subreddits so I don't have easy access to the database file for it :(((((
Same for a couple others of these.
I will try to do what I can with rescuing them but because of accessibility to the databases they're at the back of the queue.
What I can access quickly is here: https://the-eye.eu/redarcs/
This doesn't mean you shouldn't list these off though. Just that what I eventually get of them may end up incomplete. I might be able to use other projects to reconstruct their data though.
