Most stuff on reddit is aggregated content anyway (or even reposted). Can’t somebody write a script to get the top contributions of the day and “crosspost” them to a suitable sub on lemmy? This would work better for certain content than for another, but stuff like funny memes would be no problem, right? I’m not looking at cat videos from Youtube and shitposts for the deep discussion in the comments.
There’s a whole instance scraping Reddit right now. lemmit.online
Their local communities on that instance can then be subscribed to for that type of content.
Course right now memes are mostly medieval gentry and pics are John Oliver, but that bot on that instance is doing what you’re asking about.
Edit: I don’t know how well it’s working for all types of content but text based ones seem to work okay.
That’s good info, thanks!
