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.

I am targeting subreddits. Right now I've got a lot of the main ones but there's a lot of unusual names (me_ira) for example I could easily have missed.
I've just manually copied all images in this and grabbed a full page screen shot for the text. When it drops and it's needed give me a nudge and I can rebuild it.
