Is it a good (probably temporary) way to get content in Lemmy?
I don’t have a problem with it. Although, I do think “sublemmy” is a stupid word, and we should just say “community”.
In short, copying Reddit’s content is fine. Copying Reddit’s terminology is silly.
Honestly yes I think it makes sense to do this, as long as the content itself isn’t hosted on reddit. It would be cool if somebody could make a bot for mods to enable this in their communities to specify subs to pull posts from and how often.
I only do it in the other direction; cross post lemmy originals to the sinking ship.
Of course, when the lemmy post links to a video or article, the reddirt post will only link to the lemmy post and not directly to the content.
It’s a way of helping others abandon ship, which indirectly adds content for us in the long run.
