Check out !worldnews@lemmit.online. The admin of lemmit.online has set up a bot that fetches reddit posts via RSS, making it much easier to make the switch and of course not getting any ads.
Also, these posts can then be cross-posted to help us create more content on lemmy native communities. Although I do recommend removing most of the post body when cross-posting. Alternatively you can turn the cross-post into a native post as if you simply were sharing content that you’ve seen on reddit, but with the perk of not having to load reddit.
You can make requests for subs to fetch at !requests@lemmit.online.
In the end we’re just using lemmy and lemmit’s bot as a simple RSS reader, so nothing illegal or even remotely unethical happening here.
I’m not trying to say “bigger is better.” The point I’m trying to make is: if a bot starts flooding lemmy communities with myriad of links, then it will be more difficult for a smaller community to make sense of it. There will be lots of communities that has many links without comments. It will start looking like a dead village. So, it would be better if only the real interesting stuff (with high ratings) are brought in. That way, fediverse communities would have a better place to start from.
