Idea: Scrape all the posts from a subreddit as they’re being made, and “archive” them on a lemmy instance, making it very clear it’s being rehosted, and linking back to the original. It would probably have to be a “closed” lemmy instance specifically for this purpose. The tool would run for multiple subreddits, allowing Lemmy users to still be updated about and discuss any potential content that gets left behind.

Thoughts? It’s probably iffy copyright-wise, but I think I can square my conscience with it.
