You can now get reddit posts on lemmy via RSS, without any ads ;)
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.
Too bad they don't seem to be federating. Just tried signing up to that specific community from Kbin, but it doesn't show the content. Oh well, gonna keep my eye on it, regardless.
