I’ve been toying with this idea at well. I don’t think it’s a good idea to scrape all content. This could drown out the lemmy-original content, especially when large subreddits are concerned. Maybe an upvote threshold (Only scrape if more than X upvotes) would be a good idea.
I would also scrape only the post itself, not the comments. Best to have our own organic discussions here.
Finally it should be very clear that a bot is posting these things. Ideally the bot would also ensure it is not re-posting something that was already posted by a Lemmy users just a bit earlier.
I’m doing all right myself, but I can’t say the same for my girlfriend. Headaches, tummyaches, backaches, or whatever random thing it is today, there’s always something. She’s a few years older than me so I guess I have something to look forward to lol.
