I think "stealing" from reddit is fine, but the automated stuff sucks. Lemmy isn't just supposed to be a carbon-copy of reddit. Having everything flooded with reddit posts would lead to Lemmy just being a dead "Reddit archive" without original content or engagement. Just look at places like /c/AskReddit@lemmit.online , completely dead. Lemmy doesn't even have the userbase to actually engage with such a large amount of content and having thousand of bot posts will be incredibly detrimental to the community.
