Bots of this type have appeared recently, and people are asking if it's okay to use them. I'm not sure about this either, so I think it would make sense to ask users.
These bots follow some subreddits on Reddit and automatically post it to Lemmy when a post is created there.
I've seen an example site for it: lemmit.online. This instance is dedicated solely to mirroring Reddit posts to the Lemmy instance.
Maybe instead of mirroring to a community on Lemmy NSFW, we can subscribe to lemmit.online via Lemmy NSFW. This way we could have kept Lemmy NSFW free of bots. Currently, even if accepted, I believe it should be done under admin control to prevent duplicates.
I think that would be super beneficial to help jumpstart this site.
Maybe at some point communities can do it the other way around, so that the „main“ branch of the community is on lemmy and can port over the follower of reddit
